depends really what you look for in playing.... I consider myself a hardcore casual gamer (meaning I play way more games than most hardcore gamer wanabe play but I'm not doing it to do MLG or pro level gaming it's a pure entertainment I like to share with friends of all sex and age)
Me I simply hate gaming with a keyboard and mouse.... yet I agree it is the best most responsive input style but it is the shittiest one in terms of immersion realism and fun.....
I always hated the fact that you can do a 180 in a millisec or stuff super fast and all.... this is great for competitive play but uber lame for casual play.... especially when I play a solo game... I seek fun, comfort and convenience..... none of which are remotely accomplished by a PC keyboard/mouse setup unless you have a super expensive set up with a nice PC gaming long chair with top of the line mouse and armrest and yet it still not fun IMO...
for example I have way more fun playing Kinect sport table tennis than playing table tennis form rockstar.... if they did a new one on Kinect 2 with Kinect support i'd be all over that....
