All of the gods had been mortal

It would be cool if there was a world where all of the gods had been mortal at one point, and anyone alive today had a chance to become one. You just had to become powerful enough to force yourself into the pantheon. BECMI D&D certainly allowed a way for this to happen, but precious few games since have done it.

Of course, some of the existing gods would likely make a point of stomping out any potential competitors, but even they can fail. If their champion gets stomped by an ascending hero, it just might be his destiny to become a god, no matter who opposes him.

This would give long-term campaigns a great goal and even better, provide a perfect finale to a campaign, with the final game night being one or more players achieving godhood.

Alternate Names for DemiGods

While the term Demigod is useful in D&D, it's also very technical. I'd love some alternative names for them. Saints doesn't really work, as it implies they are just projections of some other god, and not god-like themselves. Ascendants, as used in the Malazan series, is a great alternative, but it's taken. Anyone have any other ideas?

Season of the Witch

I just watched the movie Season of the Witch with Nicolas Cage and Ron Perlman. I liked it a lot, though it certainly wasn't perfect. In any case, if you are a fan of Warhammer Fantasy Roleplaying, you should watch this movie. It's pretty much a perfect fit.

Dark woods, knights, knaves, and evil magic are all present. A witch is escorted in a cage/wagon to her trial at a monastery. She uses magic to foil her guardians (or maybe she's an innocent being framed).

Some of the special effects weren't great, but I liked the combat scenes, and the banter between the various characters.

Arena World

Just an idea I had, since I've been playing League of Legends. How about a world that has dedicated arenas, with champions fighting each other? Have the game actually designed for it, too. I'm thinking something similar to d6 or the Supers! rpg would work well. Heck, this is one area I think 4e D&D would actually shine. I'm not sure old school D&D would do as well.

Instead of having monsters, it's just NPC Champions to fight. Team vs. Team, or even One vs. One. Heck, powerful monsters would be champs, but actually written up with a name and history.

This would also allow different arenas. Maybe one is all ice, with big chunks of snow and clear ice sheets that block ranged attacks. Another could be a jungle, and then just a flat plain for some matches.
