Bah, I'm awful at keeping secrets
Alright, so the game is basically going to be a game where you rule over an empire. Now that I really think of it, it isn't all that original to the forum games section. But anyways, you play the role as the leader. I'd say king, but what you play as is open to you. King, general, arch-wizard, witch doctor, whatever you like. And from there, you pretty much build up your empire. Construct buildings, develop tools and technology (not that such things have not been discovered, but you and your people don't originally have them/know how to make/use them), raise armies, siege other empires or form alliances, mine the planet dry, etc.
There's a game that recently came out/is coming out that had this next part. Along with running the constructions and managing the empire's laws, regulations, and its people, there are also fairly stereotypical adventurers. While you do not "control" them, you can set up missions for them that you may be otherwise incapable of doing with a large army or people who aren't gifted in using magical equipment. Some missions may simply require that you mention a place, such as mentioning a dungeon that may have treasure in it for the adventurer to raid, but others may need rewards/bounties placed, such as having them go and kill an opposing adventurer or some such. These adventurers will have far more general skills than the ones in the RPG, and their equipment won't be as detailed, but otherwise they are still described in fairly similar ways.
So, that's about all I'll say for now. There's still more being added, and a bit of it might change, but most of what I said is pretty much set in stone by now. The storyline will come when I make the game, as well as specifics for controlling and junk. And if I see any games suddenly pop up with this general theme, I'll dig up Webadict's Flat images and terrorize your souls with horrid gory scenes of death and carnage. And not the good kind.
