I\'ve been doing some rapid prototyping for a game I\'m thinking of building. one of the main things i want to do is map generation for a tile type map. While generating the map
There's no details provided, but my gut feeling would be that the problem you're having is not lack of memory (which your system has ample) but suboptimal and/or faulty algorhythms. You probably need to rethink the way you generate the maps and also be sure that you're not ending up in an infinite loop somewhere.
If you post more details (possibly in another question) maybe we can be more helpful.
