As I posted elsewhere, here's something I found fun to discover...
... a pretty long discussion
on what I gather is a discussion board devoted to a game on how the game's alien species would react to being dropped into The Arena!
Reading it I think it stays pretty reasonable and on-target, although the participants seem to underestimate the Arena's willingness to enforce ITS view of "fair". For instance, if I understand the description they give of the "Zerg", they'd probably end up severely crippled by some minor tweak to the rules, because the Arena wouldn't want them munching their way through the sky.
