I'm still deciding whether I want to use XP or VX. I really like how XP looks and the way it's run, but I know that VX has a "built in" world map system.
Is it possible to have a world map on XP, and if so is it hard to do?
It depends on what you mean when you say "world map". The system in VX is simply a normal map with different tiles, that are much smaller, as well as ones that are miniature towns, castles, and such. This can be replicated very easily in XP, using one of several custom tilesets floating around the net. On the other hand, if you wanted a world map more like an actual map, where you select where to go by town, or something like that, it would have to be scripted, even if you were using VX.
