It looks like an old Quake 2 dm map which was scaled up for empires. But if you want to remove this one you have to remove emp_money too. On the other side it doesnt hurt to have one more map to play. You wont win a beauty constest with this map and i think the fun on it stays bounded, but why deleting stuff that is already in ?
I wouldn't remove money... now that teams don't just arty spam, but attack bases directly with APC's, it's a really fun map.
In my opinion this map should be kept, but the bases should be moved out into another area away from the tangle of paths, like in streets of fire. Make the bases dependable and so it's the resources that are fought for, and so that the map lasts a decent amount of time and is playable.
I think it'd play better as a flag cap map like cdr canyon with full research and the flags counting as resource. The res point would be flag points, naturally
