By the way, there is a thread on these forums about a remake that will be done in 3D of VVVVVV.
It's called QQQQQQ.
It was originally based off of a CoD:4 build mod but then migrated to OpenArena, the Quake 3 engine.
It's still a work in progress, but if it ever does get done, it would probably be something like this.
It's posted in one of the sticky threads at the top of the VVVVVV board. It's called 'VVVVVV Demakes and Fangames'. Terry started the thread and stickied it himself a while back to compile all those works together in one place.
So, while Terry may not be working on a 3D version of VVVVVV, someone else probably will, in due time, make a 3D version.
