Generally though your best bet is to actually come up with a great game instead of worrying about sneaky tips to gain a couple more sales.
Not to derail the thread, but this is a good point. I think I've got a great game. Of course it's my game so I may be delusional. But I am under the impression that even a great game may not spread virally.. that it generally takes great promo even for a great game.
I've got a handful of very enthusiastic players, and my game's average play time is around 20 minutes. Feedback on the game itself is so contradictory and all over the board that I can't get a good feel for what to do next. So, I think promotion is the main thing I need at this point. More players may lead to more of a consensus on what to do to improve the game. Anyway, I am really unsure what to do. I've been working on the game for a year and a half, implementing feedback throughout the process.
So.. how to know when the problem is the game, and when it is the marketing?
