PC, of course. I think that'll be the easy answer on this forum because it's for a strategy game forum. Strategy gaming on consoles, handhelds, and arcade cabinets is essentially non-existent. Gamepads and joysticks work find for action-oriented games, but they are abysmal for most strategy games. Until keyboards become standard issue with consoles, PCs will be the only truly viable platform for strategy gaming. Plus, even with the action games, PCs produce far, far better graphics if you can afford the latest hardware. The only area where PCs are inferior, IMO, is social gaming.
