Yeah, and you don't have to use your brain too much in FPS games too....
Dear sir, play me in a game of
Urban Terror and I'll show you just how much of a difference using your brain will make.
There's so much bullshit and prejudice going on in here it actually scares me a bit. FPS games require incredible amount of skill, and not just with aiming but more so in your movement and positioning. FPS games aren't about shooting straight, they're about knowing what your opponent will do and then knowing the best counter move. I've been an FPS gamer for far too many years now, and I certainly don't consider myself a stupid gamer, nor a lesser gamer than RPG gamers.
Also, just because a person prefers a nice FPS game it doesn't mean said person cannot enjoy RPG, RTS or whatever genre games. I'm a huge fan of Gothic II for instance, and I've spent way too many hours on Jagged Alliance.
Seriously people, stop being so closed minded and start looking around you, the world is bigger than just your small world, and chances are 95% of the time your opinion is most likely just plain narrow minded or based on an incorrect assumption.
Sadly, common sense is not so common any more.
