I waited six months to play it again. I turned out all the lights, lit candles, incense, got a really good cuppa ginger tea, to help with the mood. The music of that game is so much better than any other besides Riven (and I love it for the same reason).
Talking to every single random character is fun. Tiny little tidbits get filled in. I thought I'd hit every bit of dialogue on the last play-through, but I've still hit much more by going back and forth a lot, checking each character several times.
Just watched Operation Mi'hen again (and let Seymour get pummelled long enough to observe his overdrive, which is adequate, but the Aeons are better). I think I've got the spirit of Spira back in my head enough to start writing again.
