You shouldn't even worry about the Wii version, it sucks. I say PS3, because I have it for the PS3 and it's awesome! You should definitely get it on PS3 if you want add-on content, aka DLC. I assume the PC version is pretty much the same as the PS3 version, with the exception that there is NO PlayStation Store, so you are better off with getting it on the PS3 so you can purchase DLC.
PS3. Speaking as someone who plays the multiplayer on the PC. It would be nice to have the DLC maps and models found on PS3, and people who don't crack into the turret weapons all the time. The game gets stupidly unbalanced with those hacks. The wii version is cool with me. But its more of a extra entitiy for war for cybertrons fiction. I'd recommend you get it. But definitely only as a curiousity after playing war for cybertron in its proper form.
I don't know for Multiplayer, but I can't imagine that playing such a game is actually better with a joypad than playing with mouse and keyboard. So I voted PC.
Maybe other people are used to playing complex modern games with this setup and its just me. But PC gameing today with a keyboard and mouse is overwhelming. I could handle it back in 1998 when games had fewer inputs. But there is lot to keep track of in WFC. Grenades, weapon select, transform, ability 1, ability 2, scope in, jump, reload, fire, melee. And once you transform you have to consider your fireing trigger and scope become a trigger and accelerator. I may not be able to look around as quickly useing the gamepad over a mouse. But at least its a more natural management system. And driving arguably is easier with a gamepad.
Hm that's true driving is best with a gamepad, but you get used to it and I drive only to abdrige long distances that would take too long for walking. I have no problem with keyboard and mouse playing WFC. I always feel ******ed when I play such a game with a gamepad and want to aim at something or just look around. I always play with high sensitivity and with analog sticks or a d-pad it would be unplayable to me.
