To anyone still interested in this thread, I have not flaked. I was busting my ass recording yesterday, but all my videos had out-of-sync audio, and I don't have the expertise or proper software to fix those, so I eventually just gave up. It's payday today, so I'm taking the day off to drink, listen to music, watch Game Grumps, catch up on my growing stack of unread comics, and in general do nothing useful.
But tomorrow night I'll be starting...
For once, an old game actually works on my computer without me having to fight it, and while there's a weird issue of the recording only showing a black screen when I start in-game (though it seems to work fine when I start recording before I launch the game), with any luck there will be no technical issues.
The only thing that will be bothersome is that my camera only shows me as a dark blob with the lights out (and I'm not playing a horror game with the lights on), but I think I've figured out how to jury rig some lighting that won't detract from the experience.
And since I'm off on Sunday I'll be able to pull an all-nighter. Kinda stoked for this.
