I'm guessing you're into shooters, in which case the two games I'd recommend are Population: One and Hyper dash. Population: One is a battle royale (I don't really like battle royales) but the movement and gunplay is some of the best in VR imo, and has led me to sink over a thousand hours into the game. The game has a pretty healthy player base size for a VR game, with a few hundred thousand active players and decently large competitive player base and decent prize pools, so if you ever got into the competitive side of it, it's not bad.
Hyper dash is also a good VR shooter that is team based with modes similar to what you find in tf2 like control points and payload. Movement is kinda janky but it's a fast paced game with guns that feel good to use, and has a healthy competitive player base too (by VR standards).
Both games run well on quest 2 standalone and index.
