^^ On LBP, yes I agree, there was a huge community input for level design. But can you take that crown away from Quake 3 Arena? It resulted in an entirely separate design program that became an industry staple (Radiant/GTK Radiant). I would feel confident to state that the Quake 3 Arena community was/is much larger than the LBP community.
On World of Goo, there were 2 iterations of the game before the final product, the physics system was in tact much earlier than planned. That said, there was some speculation that part of LBP delays were due to revamping the physics. This I am unsure of myself, as I was not involved in the LBP beta.
edit- on RE4, have you PLAYED the PC version? It was a terrible mess of a game. They really botched the controls on it pretty badly. The Wii version was far improved compared to any other version. Also, on KB/M combos, sure the mouse is more precise, but the KB is not more accurate than the nunchuck. The nunchuck has more response over the WASD movement.
