Sigh. Tough question, and one I've thought about a lot.
I'd be fibbing if I said the sporadic nature of the game hasn't lessened my interest. As a purely RPing matter, I have a tough time getting invested in a character without regular sessions. Also, other matters (both social and professional) begin to take precedence if I can't count on that Thursday night slot being filled on a regular basis. Given the complexity of my schedule, I find it difficult to block off that time period from other commitments when I know there's a better-than-even chance that there won't be a game. Were it solely up to me, I'd probably withdraw gracefully from gaming at this point and let John get on with life.
That said, I really think we're talking the end of the era for this group (especially with John at the helm), if our experimental return to PNP falls through. I don't see us going back to NWN given the time commitment involved, or joining some MMORPG to engage in mindless questing. Maybe that's for the best; I think we've all enjoyed the games immensely, but I couldn't fault anyone for feeling like it's time to move on to other things. And we've been doing this a long time. I think that the last thing any of us would want is for our sessions to continue past the point where we're having fun, and become a burden for all of us, because none of us says anything out of concern that everyone else wants to keep going.
Yet because this is a decision point for the group, I will commit to continuing if the group decides to continue -- i.e., I won't drop out by myself (at least in the near future) if the rest of you want to keep going.
So to sum up, that's a vote to end from me, but I will continue if the majority favors continuing.
