I think the PC version pwns pretty much.
Well. I can't make anything playable for anyone who does not own both games and I can't distribute meshes (from what know) all assets are still owned by GlyphX. The very small dedicated AR community is trying to pull some strings. We'll see.
Can I have the address of that community? As always I am interested in reviving good old games. I will give it a second chance and to Halo 2 too.
PS. I am toying with unreal engine these days. I have some ideas. One for Morrowind too. I think there is nothing wrong with being hugely influenced.
PPS. Some guys tried to mod Quake 4 for Requiem: Avanging Angel. But they couldn't finish it. They released the assets for free.

If they have a tool like MGE(RAAGE), maybe fixing and polishing original game would turn out better. I really dig its gameplay. I have no idea how to hack an executable to make it use alternate assets yet alone writing a graphics wrapper or I would do it. The game is not even patchable(DX7 to DX8) on new Windowses.
