I made t4 for quake4, but although the same architecture, it felt kind of sh1t, gameplay wise.
And I made Doom2 dm1 deathmatch for Doom3, but the map disappeared when sites went down. Could not find the map anymore.

Yeah, I'm just doing it for my own amusement really, I wouldn't expect them to play well even in Q4.

I've got a few maps done to the walking around level now, the only really big problem is relighting, which is time consuming and actually needs some talent, so I'll end up half arsing it.
