You're not a AAA game studio or charging them $100 a game/DLC, right?
Not for a lack of trying.
And I'm going to do a bit of a disagree on the idea that non innovative games are the ones that tend to die off. Frankly, a vast majority of forum games die off without reaching a satisfying conclusion, both innovative and repetitive. Honestly I think it's hard to come up with games that
do conclude well, out of the ones I've paid attention too lately, Hedge lords was noticeable as being a completely new and complex in mechanically in depth 4x that managed to finish completely, and Haspens war games often reach a winner. Hedge lords was very innovative, and Haspens games are all innovative compared to what everyone else is doing, although he makes and runs so many of them you might be excused for not thinking of them as such since he invites comparison to himself
The idea that innovative games tend to die is I think a bit of trying to level something that's inherently unlevel, I think creative motivated GMs are both the ones most likely to make a innovative game and the ones to bring a game to a satisfying conclusion, low effort low motivation gms tend to be the most copy paste of previous ideas and most likely to die off unceremoniously.
You know what games really tend to not last long? Cookie cutter soft rping games, often about gods or mages or whatever, they pop up like mushrooms after a rainstorm in the FG&RPing section, none of them are very innovative, and they tend to die off after a few pages.
Edison probably did have plenty of failures, but we do remember him
for his successes. There's plenty of inventors who never made anything of worth who have been lost to time and we'd call failures.
People should not be giving you shit for quickly abandoning games because frankly that's not even abnormal. But making and sticking to a game would be good too. Especially if it's a game that people get invested in, games that are just about spamming out suggestions or doing a little task are probably not going to make people that sad if they end abruptly, but if you ask people to get invested in a game by making a character or something else that is uniquely theirs, that will feel bad when it's abandoned. Although as said I don't think that's abnormal, I would probably avoid any of your games that ask for such a commitment from me, but I would say I avoid a majority of such games on bay12 for that same reason.
