1. 360 sucks
2. 360 is Microsoft (which speaks for itself)
3. 360 doesn't support OpenGL (therefore, no Quake/2/3 ports for it)
4. How about porting Stratagus to the Wii?
Honestly, worst idea ever.
You could probably have phrased that better... the only valid argument was number 3. I might have missed it, but did anyone point out that the OA team doesn't really do work on the Quake 3 engine?
