Yes, totally agree, well we are developing a "retro" style game engine, and we need a good "test" case, and what better than Wolf3d to ensure its quality, then once finished people can use the engine to build custom (original) 3d games for ZUNE (u know zune does not support real 3d yet), and at this point we need some feedback from the community to ensure we are doing a good implementation following patterns and that kind of stuff, in conclussion we r not planning to sell Wolf3d over XBLA unless ID allows us to do that, but thats not the point, we are doing that for educational purposes and off course for fun.
