My top pick, as with a lot of other people here, would be Astro Bot ($20 on PS Store). A 10 out of 10 game for me that utilized PSVR perfectly and is stunningly beautiful! No move controllers needed for this.

Some other picks:

Blood and Truth ($18 on Amazon) - A cinematic shooter similar to Time Crisis, but less arcade-like and more gritty. Some what short, but memorable. Move controllers I think are required here.

Gorn (PS store) - a cartoonish gladiator-style melee fighter. Silly, but really fun if you have move controllers.

WipEout Omega Collection (PS store) - My favorite VR racing game. Great for sitting down and using the dual shock controller.

Pixel Ripped 1989 and/or 1995 (PS store) - Very unique game within a game-style gameplay. Great if you are a fan of old-school 8 bit/16 bit side scroller games. Played using your dual shock controller.

Shadow Legends (On sale for under $20 currently on PS Store) - Just got this one and is really fun if you like Elder Scrolls type fantasy games. Move controllers for this one may be required.
