Single-player is probably better. Although a multiplayer option could work, but then we could implement this idea. I want to improve "Utopia" in this way... Run script checks for computer/human players, and if there's a computer player, enhance its abilities. And of course, other scripts, a storyline, quests, etc. That would be great. The faction isn't particularly important, but you could choose a less common one (in the case of multiplayer, you could probably even have a free faction). I think I was looking for maps featuring Orcs once and discovered that they aren't popular among mapmakers. Accordingly...
That's how I see it. It would be interesting. We could relax and have some fun.
