The things that really stood out to me are the world map, the dungeon generator, the vehicle option back into the database, the quick events (for teleporting, doors, chests, etc), starting events for vehicles & your party, also the new boxes added to some tabs of the database for notes (I think this is a great idea, since I'm really forget and always need to write down notes about things!), as well as the new options for messages in event commands..
This seems pretty cool and the graphics are pretty good too, I especially like how they brought back some of the old features that everyone liked. But I'm not sure if I'd stick with XP or switch to this..
