I agree with LordT on 'perfection added to success'. Finishing a game is what you should strive for, it's the icing on the cake and it's very, very satisfying. But I don't think it's a failure to come up short of that. I think we should also note that there are, of course, degrees of success. To take the two examples Xan mentioned, if a A Breaking World and A Tide of Flames were both to finish tomorrow, then yes, they might both be considered successful. But ABW would be considered a moderate success that didn't really reach its potential. AToF, on the other hand, would be considered an enormous, inspirational success- after 100 pages, who could argue otherwise? As for the 50 posts threshold, LordT makes a good point about the relative size of games, but I agree with Xany that for the average game (probably 4-6 players? We'll need to work this out one day) 50 posts is a decent bottom margin.
