@Indrah: Okay, I understand. But...in fiction, the lines between magic and science are often blurred. They often do the exact same thing, just in different ways. Like, instantaneous teleportation! In fantasy, it's magic. In sci-fi, it's technology. A modern setting doesn't HAVE to be like real life. Maybe cars run on magical energy? People use fossil fuels in real life, which are kinda fuels developed from dead organisms. Doesn't that sound like some bizarre necromancy? I'm just sayin', modern technology and conveniences can easily be MAGICAL if you just think outside the box...So...why not space travel? Maybe we could have magic portals. Maybe spaceships could be made with magic? And powered by magic? Maybe there's some kind of dragon that can fly through space!?
I'm sorry, I ramble about my weird ideas too much. From the first RPG Maker, I've always wanted to mix stuff around! Like, why not mix medieval fantasy with modern stuff and sci-fi!? If that doesn't have a place in Arum, that's fine. After all, I need to take a break from my "cyborgs versus dinosaurs" ideas sometimes. (just an example! not saying I do that...even though I do...)
So...well...planets as dimensions is already free reign huh? Makes me think of all the different Planes in Magic the Gathering. (but, like, more varied than that, almost every plane has to have humans, there are almost no guns, and between all those different worlds, the technology level can't break past a certain threshold...not counting the Borg-like race and the countless "artifact creatures" tee hee hee)
