Sure, we do know that Quake 4 is being developed by Raven Software and is using the Doom 3 engine, but is there anything else to know about the upcoming sequel to Quake 2?. I remember reading somewhere that it is a continuation to Quake 2, is that accurate?. I just hope Quake 4 shows more ingenuity in game design than Doom 3, and has a much more involved storyline/world. Hopefully, in the next few months, we'll see some more info on it.
