Whoa, you guys talk too much
I'll just say one thing and get out.
When I play with the Wii controller, which is split up into 2 different pieces that move independently from each other, I don't feel as if I'm in control of the controller, and in a way, the game. It just feels loose. In games like Mario Kart, SSB and stuff, I
need to feel in control - these are fast paced games.
The same thing goes for 2D platformers - there are a lot of sections that need perfect timing, pinpoint jumping or crazy amounts of button pressing.
