I've been streaming a bit lately doing a survival challenge thing where I start at level 1 on a lava world in empyrion. You get out of the pod and it's 300 degrees and you have nothing. It's tough. I burned to death alot, but it was entertaining.
Once I made it into orbit it got rather dull though. With most of the survival stuff I like the surviving bit only lasts the first few minutes.
It got me looking into twitch extensions. There are a few games that would be really cool if viewers could "do stuff". Like throw buffs or debuffs at you or gear. I could do it in empyrion as it has a plugin architecture going. I wrote one to do a simple hacky permadeath that restarts you if you die.
So I've been trying to think of a cool game to do in an interactive way like that. I don't talk or do the whole stream of consciousness blather that streamers do, so viewer funbuttons would help with my total lack of personality.
Survival games are an obvious candidate. Also I was thinking an elderscrolls like tying into open morrowind. Skyrim would be cool but I'm not sure how I'd connect it to the extension stuff. Maybe an xcom thing where viewers could give a % boost or penalty to the next shot? I dunno! Give me ideas so that I might steal them.
