I used to have a melee map like this one:
$?Fa§te§t Po§§ible Map Ever?$ - Warcraft 3 Maps - Epic War.com

I don't remember if everyone had three goldmines, but besides that, the only difference between this one and the one I had is that instead of water, walls separated the players. So it had a squarer look.
Also, I believe there was a fountain with some tough creeps in the center.

Does anyone know where I can find/acquire/download such a map?

Thanks to anyone who read this :D
