Hatsune Miku: VR Future Live is probably my most-played game. This game isn't for everyone, but if you enjoy jpop/idols/Miku, you will probably love this. I usually get at least one concert run in before turning my headset off. Some great songs, outfits and performances. It keeps me coming back. VR makes this great because you can look all around the concert. And while you can only teleport to certain parts of the concert, you can still walk around the somewhat-limited space that the PS Camera can track you and get up close to Miku and walk around her.

The latest game I bought was Robinson: The Journey, and it was also a lot of fun. Great little sci-fi adventure game with some awesome-looking dinos and great looking environments. Probably the best-looking VR game. 8/10. Paid $40 for it for a retail copy, it was worth it. Wish the game was longer, though, because I was thoroughly enjoying it. Probably took me about 6 hours to beat. Some stuff to search for and do after the game is over if you didn't already do it, too.

Brookhust Experiment is a hidden gem; survival is a blast. The move controls work great here, I mean you can aim down your sights on your gun as you would in real life, and pull off headshots. Really fun game.
Rigs is one of my favorite VR games. I liked it more than I thought I would. Online is super fun, but I find it hard to find full 3 on 3 games, which is a bummer. Still, most people have mics and I've met some great people on here.
Eve Valkyrie is a fantastic space shooter. I haven't even played the campaign yet, just the tutorials and online play. Looks great and plays great. It's a lot of what I would want from a space dogfighting game. This was the first VR game I ever played; it's the one I demo'ed at Gamestop and convinced me to get VR. Every time I play it it impresses me just how well it works in VR.
Thumper is a decent rythem-type game. You can play it without VR but the VR experience is pretty cool. Not my favorite type of game, but it's decent.
Here They Lie is a pretty good horror game. Walking around the apartment buildings outside is a very realistic experience, and the horror elements are fantastic. I find it hard to find movies that scare me, but this game freaked me out later on. I like it, need to find time to play this one some more.
A couple weeks ago I played co-op through the entire Battlezone campaign online for about 2 1/2 hours with 3 other guys until like 2 AM and had a blast. Haven't played this one too much, and I think the graphics could have been a bit better, but that night was cool!
When PSVR launched I played it with my family and London Heist from VR Worlds was the most-played game. I actually haven't played it myself because I've seen others go through it so many times. But watching them light a cigar and smoke it was priceless (breathe in and out to smoke it in game!). Ocean Descent is a great experience, even though it's not really a game. Luge is alright, it's kinda fun. Probably my least favorite. Space Odyssey was quite enjoyable. Probably the longest experience on here and quite a bit of fun. Danger Ball is a fun arcarde game. I got this with the PSVR Bundle. $40 is about right, maybe a bit pricey overall.
Can't wait for some more awesome VR games to come out! Will get Job Simulator when it drops to $20 or lower.
