I'm looking for an engine that can handle a few things.
- 16 - 32 player multiplayer
- can handle large, mostly empty worlds
- Ability to change gravity on the fly, per-player
That's about all the main stuff I'm looking for. I've been looking at the UDK ,Source SDK, and Unity. Unity is slower than a turtle, and the UDK has an odd feel to it. I haven't messed around with the Source SDK mmuch yet, but it seems that it will do the job well enough. Any other semi-decent engines I could use? I'll give specific information if you ask.
