I'd be up for it but I'm not particularly interesting.
And nobody knows who the hell I am anyway.
For a FF7 game commentary, since it would be so long, perhaps it could be done in 'shifts' by different groups if there are enough people that want to commentate. Like, for example, persons A, B, C and D commentate from the beginning until leaving Midgar, then persons E, F, G and H comment for another stretch of the game, then back to the first group (or a third group) and so on. It would also get it done faster.
