Hello!
A lot of people have been talking about the camera, the defects and issues with firmware bugs, and whatnot, but I haven't seen much info about how games feel on this phone.
There's quite a lot of power in this thing, and it has a 3000mAh battery (twice as much as iPhone 5s), but perhaps suffers from lack of truly optimized software. Some games feel good on Z1, while others not so much. For one, the home menu bar is sometimes getting in the way, due to the fact that it's implemented as part of the software, not the hardware itself. So, in some applications it will get in the way, cutting a small part of the left end of your game. This cut-out will be of the same size as the menu bar, so in a way it's quite a problem. It could be argued that the home menu bar is needed, but I often end up triggering Google Now, or accidentally pressing one of the three buttons. This can be very annoying, and sometimes game breaking if you playing a PvP game. I believe this issue can be easily fixed with a software update, something to prevent accidental presses. Maybe an option to hide it, and activate with some kind of a sequence, like 3 taps somewhere on the screen, or something like that. Come on, Sony, you are not new to gaming. Be creative with the software and fix this.
Now, to get to the list. These are the games I've tried and really liked so far:
FPS:
Blitz Brigade (Feels really nice with Gyro controls. It feels funny to stand up and just hold your screen and move both of your arms around. 100% sensitivity makes it quite accurate and removes the issue of 2nd pad vs. shoot accidental clicks/missclicks)
SHADOWGUN: DeadZone (This game is amazing, really. A third-person shooter, which instantly makes you addicted to it. I immediately entered a multiplayer game upon 1st launching the game, and managed to score 2-3 kills, though I got really lucky. The aiming and moving around felt OK, but I am still very new to this. An experienced player will be much better at it than me, and could have some criticism that I can't think of right now. Anyways, great experience - I recommend it)
Critical Strike Portable (Well, this game pretty much looks exactly like CS as you know it. Not that the actual CS looks that good, heh. Still, it's amazing to have this shooter on your phone and I have it installed on mine. Would make for some good old school fps MP action)
Rivals at War (There are a couple of versions of this game, both basically being clones of each other, only one is set to be a modern combat shooter, while the other one a sci-fi futuristic shooter. I honestly don't know much about these games, and I have the futuristic one installed. It looks interesting and I plan to give it a try)
Dead Trigger 2 (Amazing FPS game, runs on Unity engine. It's free and absolutely beautiful. The controls feel good, there is auto-shoot mode for the lazy, which can be turned off, and the atmosphere in the very beginning even slightly reminds of HL2. I recommend this game to anyone who has any interest in shooters! It's a must-try, and you will not be disappointed. Expect the need to have a cosntant internet connection if you want to play this. It's a downside, but not such a huge one. The game also has graphics settings, so if you cannot run it well just try to reduce them to Low. If you have a nice devce - try the highest and enjoy one of the most beatufil games you'll play on your Android device today)
Dungeoning (RPG):
Dungeon Hunter 3 (I played this game for a while, and I can say it's not bad at all. Visuals are slightly weaker than DH4, but they are still good for a pocket game. If you are a fan of hack'n'slash - this title is for you. I hate p2w games, but I don't feel like the gameplay is bad if you don't invest a single cent into it. The game is also more challenging this way. Your hero selection is not large, and aiming is probably a slight bit harder than in DH4. I take this as a plus, to be fair)
Dungeon Hunter 4 (Well, the graphics are kind of 'stunning', given that this is a game for a phone. I always pick the Archer when I play these games, and I can say the archer experience is not bad at all in this game. Unlike DH3, you don't immediately start off with two weapon sets, so you have to work with your bow for a while. I played a wave challenge, it's really an addictive thing. Once you spend your initial potions - you will have 0 left with almost no way to get more, and 1 or 2 free per 24 hours on a timer. If you want more - you gotta pay cash. So you virtually have 0 potions if you want to go on the full-on-free path. During some challenges, you have to withstand dozens of waves with the same healthbar, with no potions, in order to win. This includes the final boss. It's quite a thrill, and drains a ton of battery when you die a lot and refuse to give up :))
Strategy-like:

Nice, I am adding myself to the request that Sony should allow us to benefit from full size of the screen in games, and menu bar should be activated other way, for example fast type Power button 2 or 3 times.
It would be really nice to benefit from entire screen when gaming.
Can anyone pass it internally?
Thank you.
The other thing is I hope Sony is releasing the latest driver to Snapdaragon 800 with every update to the phone.
I really hope they keep optimizing the software for Z1. I just received the newest Android update an hour ago, so I'm eager to see if there is any improvement. Allegedly, batter life is better with it. We shall see.
You can go into the playstore and download full screen it's a very useful app I've been using it since my Tx and now with my Z1 once activated the on screen buttons are gone.https://play.google.com/store/apps/details?id=de.tsorn.FullScreen it works for me should for you guys as well.
Thank you, this is a great suggestion, but it says that it requires root. I haven't rooted my phone and I am not really in a rush to do that (as there isn't really that much of a reason for me to do that while the phone has 2 years of warranty). Or does this app actually work without root?
I was lucky enough to find an app, which allows you to turn-off this Google Now thing. I am actually amazed that Android does not have an option for this already. It goes on to show that there is practically no legal mobile OS which allows you to take full control of your device. OK, I get that some people might mess things up far too often with that kind of control, but really - not being able to turn off Google Now? I will never, ever use this application, not because I don't like it, but because it was shoved in my face. Because I keep accidentally turning this piece of when I am playing games. Because I don't like having invasive software on my phone when I buy a high-end device. So gladly, people have found a way to help other people like me, and now the Google now mechanic does NOTHING. Like I always dreamed about it. Now I just need to find a working app that allows you to go fullscreeen whenever, as I still keep activating my multitasker when I play games. Who the thought this was a good idea when they were making such a potentially great phone for gaming, I do not know.
Dead Trigger 2:
runs good on our Z1 at high preset 
Good controls, nice graphics, story mode.
I should be embarrassed for forgetting to add this game on the day it got released. Added it now. Dead Trigger 2 is amazing, easily the best-looking game available for Z1 currently.
