Tentatively interested!

Are there going to be actual mechanics to fighting and other hero activities, or are our "builds" more like guidelines while keeping things freeform?

The only mechanics that will exist will be for combat situations. And even then, I wouldn't really call it "mechanics". While things like auto-hiting and insta-gibbing is certainly not okay, what you guys will do for the most part is:

1. Describe where your character moves and what they see.
2. Write what action(s) they take and what their hoped-for/desired result would be/do.
3. Wait for my GM response with the actual results of whatever you did.

There's no dice, no rock-paper-scissors, no drawing or flipping cards.

Your skills and abilities are described wtih details on what they specifically do, and then you, as the player, use those abilities as they're described.

Example: You have an ability to let's you conjure and shoot a bolt of fire in a straight line, wherever you can see.

That's the only "mechanic" for how your abilities work. There's no limit on how many times you can do it, or in how long of a "cooldown" you need to take into account. Just as long as you're reasonably [b][i]reasonable[/i][/b] and don't go full Gary-Stu/Mary-Sue and just start trouncing everything and everyone around and never ever missing, breaking a sweat or getting tired or feeling any sort of pain or injury, you should be good.
