How cool would it be to have a BFG edition of Quake 4, together with Quake 1, Quake 2, Quake 3 and all expansions, remastered in HD?

Very, especially if they finally fix all the weird performance/graphical issues with quake 4. I tried the Q4 multiplayer last night and it was a sad sight for a wide variety of reasons

If they wanna remaster all of them though, I'd throw money at them for sure.
