I'm not sure how to Philip's contribution. I'll think of something.
I suggest a giant flashing neon arrow with "MOST AWESOME CONTRIBUTOR" next to my name. Or nothing at all; I don't mind
Do we need to distinguish active and retired members at all? I think the important thing is just to give people credit for work they've put into the game in the past, and it doesn't matter whether or not they'd retired at the time we last updated the credits list. Also it'll take extra effort to maintain the active/retired status over time as people's status changes, and I'd like to avoid effort if there's not a clear benefit.
he should be mentioned although it doesn't seem likely any of his music will appear in the final game.
Yeah, I don't think it should matter whether their work survives - they did work for the game and deserve credit for it regardless of what happened afterwards.
A few randomly noticed typos and missing data:
Should be "Phoenix-..."
Real name: Michael Reiland
perfect - Nicolai Hähnle
Real name: Poya Manouchehri
Probably-incomplete list of other ancient programmers (mostly pre-CVS and generally none of their work survived, but they seemingly had some non-trivial influence on the code design): Dak Lozar (Dave Loeser). Raj Sharma. h20 (Daniel Wilhelm).
