No, no, no. It's not because it's bulky, it's because of the analogs and D-pad position. It's totally not for me, as there are button configurations for lefties and righties, but not for ambi-dextrous people.
When I run with lefty configuration, it's on the look analog, instead of movement one. The movement one, when pressed is for knifing.
(Oh wait, this doesn't relate to this game at all, but IF I wanted to play shooter games? That'd be annoying)
And I use(d) my PS2 controller to play LFS on my laptop all the time, until it broke. It must've made my brain think that no other configuration is better for driving games.
