Yea, actually I didn't even state that it has to be epic, all I wrote that it should be a non-marathon game and it should be a big map like huge or large. There was a gauntlet nearly being released on rainforest map with Darius about 1 or 2 years ago, I think it was a space race game but I can't remember the game speed (it wasn't marathon, though). Anyway, that has been canceled in the very last moment before the competition could have been started.
I still think it would be a fun game as rainforest requires a unique strategy as you have more than plenty food but just a limited hammers, and both health and luxury resources are limited too. Well, you have dozens of pigs, rice, and later on bananas, but that's it, anything else are rarities, if you are lucky enough, you can find some other animals and grains to improve your health bar, but it is nearly impossible to get any seafood outhere.
So, I would love to play that gauntlet this time for real!
