I would appreciate a more in depth description of what you're trying to get at. I personally like the idea but I'd like to use Sandbox and if a contest was for some reason to be held with the matter of building castles I am sure at this point and time the Mythic Map Pack would be excluded since everybody unfortunately doesn't have them.
I reckon this would be quite good fun! I suppose you might have to wait until the Mythic maps are released on the XBL marketplace if you wanted to use Sandbox. You could probably even make it a template contest. It would certainly be nice to see some more castles made.
Besides the fact You should ask this Thread be moved to Suggestions. Yes, I actually Agree. WE have many maps now, foundry, Sandbox, and Avalanche. So we would see a very good batch of variations, I know I'm no buddy but I'll say when I hear a good idea. Maybe call it the Castle Crasher Forge Contest, It would be very similar to the SHell Shock contest.
i've been in very early development of making a 'sand' castle... with 2 gametypes, 'castle crashers' and 'storm the gates' although i'm having a few issues with the towers at the mo... but i'm down for a comp to build it... would mean i'd make a good start on it and work hard on nutting out the problems..
