Nothing motivates me like an unlockable character that hasn't been unlocked yet.
Inspired by NaNoWriMo's "magna carta"s, this is a list of things in games that I've liked.
They are here as inspiration, motivation, and as a tribute. I hope to borrow/steal/remix/create with this, to give my own games a bit of the joy these brought me.
These should help step towards the principles I care about in games. What themes are threaded through all these?
