Don't expect your game to be a hit, and move on if it doesn't fly

Don’t blame the situation. Don’t blame the competition. Don’t blame the audience. Your game just didn’t fly. There are lots of really incredible games out there and even though people might give you a lot of positive feedback about yours – well, compliments are free. It’s hard to predict what people will actually buy. 

Just move onto the next one, keep your momentum, and focus on a new concept.
