i play Doom more than i do half-life 1. but that's probably because i've beat hl1 at least 10 times, and i'm now finding more and more Doom wads that i've never run through. and i still haven't ever played doom 2 all the way through...DevilSShadoW said:HL1 was the first "real" FPS I've ever played. Sure you could count doom and wolf3D but in my book, the FPS chapter starts with HL1.
on topic tho, half-life is the beginning of what we now know was first-person shooters. doom is just a light-speed slaughter simulator - which is awesome in its own way
