Far as the games I've played go so far:
GT7: THE must have game. No question what so ever, this game should be in the conversation of game of this generation.
Moss: Visual improvements are very nice. Great clarity overall. The way boundaries are set in PSVR 2 makes the game more enjoyable to play than before and hand tracking is makes the experience seamless.
Job Simulator: You need plenty of space for this one otherwise the game won't even boot. Thankfully I have a large living room but it would be a shame if someone in a smaller space payed for this game and wasn't able to play it. Begs the question how many games are going to require room scale to play and will it be made more clear so people aren't screwed. That said, the whole family had a blast taking turns playing it and playing a room scale game is much different than the others. Having to walk around a large space brings a further level of immersion that's intuitive and introduces some interesting gameplay elements since you have such a larger play area.
Beat Saber: Hand tracking works perfect. For such a simple game the colors pop and everything looks gorgeous. Very fun game overall. After about 5 songs I was able to bump up the difficulty to hard.
Pavlov: Graphically the weakest game of the bunch I played over the weekend. VERY immersive game however, the controls require you to be a bit more realistic than necessary. It's cool being able to grab a magazine, pop out an empty mag, put the new mag in, chamber the first round, stabilize the gun with your non-dominant hand, sight in the weapon and fire...but in a gun fight...it becomes very chaotic and at times frustrating. Things work as they should overall but the mechanics make for a pretty steep learning curve. I can see the potential of the game, but the mechanics pushed my attention towards the more quickly accessible games I had at my finger tips.
Resident Evil 8: Holy crap the graphics are incredible and the sense of scale is impressive. I beat all of RE7 in VR and thoroughly enjoyed it. In RE7 the graphics did have pixelation and edges were jagged with generally poor anti-aliasing throughout the whole game. This has become more apparent to me now that I've experienced the level of clarity in the PSVR 2. Controls in RE8 are intuitive and hand tracking works very well. Coincidentally, Pavlov could learn a lot from RE8. RE8 adds a level of realism in its mechanics like Pavlov however, everything feels easier to do overall. To heal, you gesture to pull open your jacket and you find your healing item inside your jacket. On the right side of your jacket is your flashlight. Aiming feels great and it's the biggest difference in terms of gun play vs any other shooting vr game I've played. The eye tracking inside of the headset along with the great hand tracking makes landing shots a breeze. That's not to say it's on some kind of Red Dead Redemption auto aim. You still very much so have to aim properly, but the whole mechanic feels very natural and doesn't feel like you're struggling with controls to do what you intend to do. Everything happening in the game feels very much so like an extension of yourself. *This is the only game that introduced nausea for me. I can't say what it is just like in the past. To be fair, I did play this game last after uninterrupted hours of VR gameplay across a bunch of different games. RE7 used to make me nauseous after about 60 - 90 minutes. Overall, the bit I played was very impressive and puts it in the must buy category.
Horizon Call Of The Mountain: A beautiful game overall. Amazing sense of scale, great hand tracking, and mildly interesting story. It does a great job of serving as the "Astros Play Room" experience PSVR 2 needs. At $60 though...it feels out of place. The game doesn't suck at all, but it's obviously Sony's tech demo from the way they introduce each mechanic in the game and how it showcase each feature of the controls and headset capabilities. Again, it's a great game, I just couldn't help feel like this game should have been free with purchase of the PSVR2. That said, I do have a complaint about this game which is remedied with a simply options change. The walking is counter intuitive. They tried to take the semi realistic approach by having you swing your arms to walk. (Again...back to the point about the game feeling like Sony's tech demo of the platforms overall capabilities). This can be disabled in the options and substituted for movement with the stick. The default walking is just....silly to be honest. It isn't gaming breaking in any way, it just isn't nearly as smooth as just pushing a stick in the direction you want to move. Overall this game serves as the "oh you've never tried VR at all? Check this out!" If a person had tried VR before but not PSVR 2 I would immediately sit them down and have them play GT7.
As I'm typing this, I get excited just thinking about getting back to play GT7.
Secondly I'm excited to finish Moss and finally play Moss 2.
Beat Saber is the perfect "I only have 15 minutes to play" type of game however, it's suitable for long sessions as well.
GT7, Moss, and RE8 feel the most like the future of gaming over everything else.
Nothing on a television comes close to the experience of these games.
