It's just really nice to see a videogame that's primarily concerned with the quality of the gameplay. It's just really refreshing.
I know a lot of people like the story telling aspect of games, I guess it can add another dimension to it.
Having grown up on NES and SNES it's really nice to see a game that's just totally focussed on the gameplay.
Doom discussion, who played 1+2 on dos? I've been playing through 2 on an emulator recently.
