I think this is aimed for all the people out there who are starting to create a game or a mod, We/I would like to make games on good physics engines (Source Unreal 3 Doom ect.) But all these engines are great but the thing is if you wanted to make a game or a mod which one would you choose? A great idea would be to implement each engine to each other to make one unholy super engine like UnrealSource or something, that would be seriously like... Wow. Even though it would take like several years to like get a *.utx file to run in Half Life 2 I'd be prepared to wait. so we could have some real next gen games. NOW WHOS WITH ME!
