The Iditarod (tentative title)

So I'm going to make a game based on the Iditarod.

Right now, I just have a few things figured out:

Semi-procedurally generated lands to race through.
You are going to actually race against CPUs.
Each session is going to take several hours (so I'll probably need a save feature).
You're going to have to use your own judgement to find a good place to sleep - always a chance to die in your sleep.

On the fence about whether or not I should make any adventures into caves a text adventure section, as an homage to Colossal Cave Adventure.

Also on the fence about making either some sort of co-op mode, or a competitive mode. Not sure how well that'll work out though, since I'm planning to make sessions take a few hours.

I have how I want it to work out stylistically figured out, as well. I'll put up a few assets when I've got 'em.
