After the latest polls about ranking and coop, maybe polls inside the game would be a nice feature.
They could pop-up after entering, the advantage over the polls in the forum ofc: Every player would be reached.
I think it would give an better overall impression, as probably more players would vote.
Ofc only "important" polls should find their way in the game and maybe there should be an option to deactivate them, if an player dont want to vote at all.
Just an idea.
