I like:
The original Destruction Derby, that one is the best... I remember when MTA was released, we played that map on a server for like 15 times in a row....
Break, pretty cool and simple.
I don't know the name of this map, its something like break but instead of those models, they use windows. I made a copy of that map cause i couldn't find it but my version is crappy.
So... i like DMs, max size: something like the original Destruction Derby, minimum: really small!
