I came up with the idea of making a map of Frostcrag Spire on Avalanche. People who have downloaded the Wizard's Tower DLC for Oblivion will know about it. It is basically a big tower, with lots of spires. In the game it has teleporters going between each room. Anyone can take this idea if they wish.
It wouldn't work so well, maybe if you could make like, a set of maps. One for a generic city, then all the DLC houses, and maybe a dungeon, and maybe one generic wilderness area. That would be 7 maps, then include a starting area in each one for choosing a "class." One warrior, with maybe an energy sword, frags, and a magnum. A ranger with a sniper/beam rifle and a Br. Then a mage, maybe some plasmas, maybe even firebombs, with a plasma pistol/plasma rifle or something. Then you'd have a whole Oblivion set of 7 maps, then just make a nice gametype. Just a thought.
That would indeed be cool... and hard to make with the scenery on avalanche. Nethertheless, it would be awesome.
