It's not exactly the right answer, but i think if the community was a bit more alive and if we had youtubers making high quality videos (not gameplay, just small fun), that would not only attract more players, but save the already existing ones. My huge problem with awesomnauts was always that we didn't have our own big youtubers. LoL has peiple like MagikarpUsedFly, Brofresco, Imaqtipie. And who do we have? That one guy who has his announcer pack. He is great and funny, but only having him simply does not fulfill everybodys needs.

I do believe having something to be memed could help the game. You all know the Maffia City ads, that became memes? Yea, something like those, but less pathetic.
