I'm quite tired of these debates myself too, and the last time i changed the first post (and thus the contest rules) was when Pyritie asked me too.
I appended 'Mini' to this contest in the aspects of short play time, small terrain size, and small file size, because it wouldn't be nice to play a 5 minute game while waiting for people to download it for 15 minutes.
If you manage your imports correctly, or smartly, you can replace nearly everything in your map that you would need, however this isn't a total overhaul of the Warcraft 3 look contest.
Besides, since, as Raven0 said, 'mini' stands for a brief gameplay, without complex controls. And Wherewolftherewolf said that the game takes a relatively short amount of time to play, thus often meaning in a small area, or simple premise, etc. etc. You wouldn't need a ton of imports anyways.
I'm tired of this, and I hope that when/if this 'debate' is over another one doesn't spark up, I've been wanting to make a mini-game map for this contest since i first posted this idea.
