I will never understand PC players crammed up against a tiny monitor at a computer desk, pecking away on a keyboard.
The TV's we have are 26-27" SD tubes. My 24" computer monitor, at short range, is soooo much larger and clearer. It's not "tiny" to me at all.

Using a keyboard is also weird.
Personally, I can't imagine using a controller for most of the games I play on PC. And I've been using a Playstation controller since the PS1, so it's not that I'm "anti-controller" in general. I just separate "PC" games from "console" games. I wouldn't play a platformer or JRPG or sports game with a keyboard. Just like I wouldn't play any FPS or WRPG or RTS with a controller.
edit: you know, I think that's the problem I'm having with Bastion. That's a game that wants a controller, but I got it on PC from a Steam sale. Didn't enjoy it.
