ToME: the Tales of Maj'Eyal

Is it possible to make a Te4 game with more than one world map as if they were stacked like a dungeon? each layer would still have a fast travel zoomed out version but there would be um, about 100 world maps and about 300-500 dungeon floors, is this possible? lol I know its a lot but to make a full game like im thinking of would turn out awesome

Well i'll just say it, its for a fan-made Sword Art Online Te4 game, the full experience with all 100 levels and 3 to 5 floor dungeons between each level

I expect it could be done.

Awesome thank you i wasnt sure if it would be too much for it to handle
