there is this one gamepad with four controllers in one cord
I understand what you're saying, but only emulated games and really old PC games would benefit from that.
Crysis, etc don't have that feature.
And, seeing as you have to own the game itself before you can use emulated rom's on a PC, it is sort of defeating.
I, personally, would be overjoyed if developers considered people plugging in that sort of device and playing on the one PC. It would really kill off the need for consoles altogether (this isn't a PC supremacist thing; but it would be cool to roll all the devices into one completely).
multi input? does your pc only have 1 usb port?
i was playing lego star wars with rug on my pc not long ago
No. I mean plugging two mice and setting them to individual controls for two characters in a game, like consoles do.
