u're right, DAD. if larian implements real-time scalability in their graphics rendering for the game, it'll be ground-breaking. or not.
i've seen or heard of games that have scalability in their game graphics engine. for example, total annihilation: kingdoms. but then it's all true 3D. & no zoom. so with zoom available with your suggested method, yeah DD2 can really be a groundbreaking game.
game on!
