Bulletstorm actually took a bit of skill if I remember correctly, if you just shoot everything your not going to get very far. Its not a traditional shooter by any means though, its more points based then survival based. The kills don't really matter so much as how you killed someone, it feels very much like an arcade game almost.
Erm...I finished that entire game by just shooting everything. Perhaps if I would've cranked up the difficulty to maximum, it may have been needed to use all that "cover" that was littering the place, but other than that...no. And aside from the points system for creative killing*, it was about as standard as it could have been: retarded humor, a man in a sexy woman's body, a sarcastic general, explosions everywhere and enemies that immediately start shooting for no reason.
@[member='Lanlan']: I understand what you mean, but please refrain from calling it "real". Call it frantic, up-close, arena-style, twitch-style, or something similar...but with a name like 'real', you'll only rub people the wrong way (besides: it's pretty stupid to call a game like '
unreal tournament' real).
Anyhow: as for games, I'm mostly thinking UT2004, UT3, quake 3 and 4 (though I've heard 4 wasn't that great) and the freeware warsow (though I wasn't impressed at all when I tried it a couple days ago).
In "adventure-modus" (basically you vs a horde of relatively stupid AI's), the serious sam games are the most fun. And half-life, obviously. Oh, and painkiller, come to think of it.
*...of which you ran out of combinations somewhere halfway the game...which made the rest a repetitive grindfest. And it wasn't even a long game.
