I'm probably a total moron for even suggesting this, but for some reason Pilotwings strikes me as a great game to make a TAS for. It's an early N64 game that a good amount of people have played, it has varied and vastly different modes of play, and with the exception of a few of the hang glider levels it's pretty short. There are probably a number of ways the game's ranking system can be exploited, which could be very interesting.
There are some videos from Stefan Mahrla
here. Check out the "Sky Diving - Fast Landing" video for an example of how corners can be cut quite drastically--and it's probably possible to open your chute even later!
So, I'm just wondering if anyone is a big enough fan of the game to do this. I like the game, but I'm absolutely no good at it and probably would be absoltuely incompetent at optimizing and seeing which methods work best. Also I think I'd kill myself trying to go through some of the hang glider levels at anything less than 100% speed. :P
