To the people claiming that you need to be able to press 10 keys at once, I ask: why? I can't think of any reason why a person would need more than three or four keys pressed at any given time. Sprinting forward while zig-zagging with the strafe keys is about the most multiple inputs I can think of, and that's only three buttons at a time. Most good-quality keyboards can handle at least three simultaneous keys, so it's a non-issue.

In any case, the OP's question about whether gamepads will be usable. Since they are simply joysticks in a different configuration, the answer is yes. How playable the game is when you're using one is a different story, and highly dependent on the gamepad, the actions bound to it, how it's used, and the player.
