Death match is nice. If anything make something similiar to Morpheus 3 (morpheus 3 is a map on UT2004 for those that dont know about it) for Lugagu 2. IT's nice, has platforms, you can fall to your death, and low grav is on by default
Survival is nice, but make sure it's in an enclosed place, otherwise someone could run off to one of the corners of the map and never die. Or just take a section of the map and condense it.
Anyways, these should be considered the ramblings of a madman. it's 2:16am. Give me a break.
