I'm not a forger, never will be, but I love playing forged maps. Complex was and still is, in my opinion, the best multiplayer FPS map ever made. If someone were to recreate this in forge, I would consider them a little less than a god. I think it MIGHT be a little too big to do in foundry, but I still think it could be done with a little creativity. Here is a refresher course. http://youtube.com/watch?v=lW_6AX603xc edit: Oddjob was so cheap.
i have actually thought about complex several times while in forge... i think the ceiling of foundry might be a little low for the multiple levels of complex though. there are 3 different levels if i remember correctly, but my n64 is a 3 hour drive away. complex would be fun to play on halo 3, and you could finally JUMP!
I remember seeing alot of Goldeneye remakes when looking for Halo ones. Here is an easy way to find them: http://www.google.com/search?hl=en&q=+site:www.bungie.net+complex+remake+forge
