How many titles were even on Steam in 2003?
That’s before HL2, and it looks like the first third party titles were added in 2005, so I guess it would have just been Half Life 1, Team Fortress Classic, Counter Strike, and maybe a couple other things that are mostly forgotten today.




The term roguelite predates roguelites having meta-progression. Games with procedural generation and permadeath that aren’t turn-based tile-based crpgs are roguelites.
If this game is a roguelike, then Doom is a point-and-click item adventure, and Asteroids is an FPS.
