Infinity Ward's Robert Bowling needs your help. According to his twitter, his company is designing a controller for Modern Warfare 2, and wants to know whether you prefer concave or convex grips for the analog sticks.
This is a question I have never considered seriously before this moment: When you think about it, though, one of the main differences between the 360 controller and the PS3 controller is the convex vs. concave thing. On the whole: I prefer concave sticks, as they tend to be the slightest, teensiest bit more stable, but the PS3 convex sticks have never been a problem for me either.
Anyway, the consensus from twitter users is strongly in favor of concave design. Weigh in at the link below.
