I agree with Mersu, you guys seem to have found your niche in multiplayer maps, and I love it. And at the risk of sounding like a broken record, I would LOVE to see more done with the Prismatic concept, perhaps even within a multiplayer map. Another interesting thought is a "nothing but communication" map, in a similar vein to the Wisdom/Power/Courage puzzle in TiNLC. That was, without a doubt, my team's favorite puzzle from the original TiNLC, and it would be cool to see an entire map surrounding the necessity of communication between all players like that one puzzle did. And one more idea, though it's probably more trouble than it would really be worth, is the idea of a map that could dynamically scale it's puzzles to fit groups of varying sizes, say anywhere from 1-4. Again, just a thought, and probably not worth the effort to implement, but it would be cool nonetheless. At least, I think so.
