256x256 is already large enough. Are you sure you can effectively fill the whole area if you use larger size? Just giving food for thought.

can people already start not living in past and start linking, and preferably start using 2.0.7? It is a lot better, no RoC that would pop antivirus popups, Sharpcraft that actually doesnt, kloader, Cohadar's and Vexorian's JassHelpers both in one pack, campaign map compiler, possibility to add anything to external list of tools in the editor
Show me some succesfull, completed projects that use 480x480 map size.
