I can think of a handful of games that, despite being games that I’ve enjoyed, never really became part of a “genre”. Do you have any like this, and if so, which?
Are they games that you’d like to see another entrant to the genre to? Would you recommend the original game as one to keep playing?

BLARP! I suppose it’s a physics game but I’m not aware of anything else quite like it. It’s incredibly simple, addictive, and could only really exist as a VR game.
