Yes, for an MMO and with classes, it's definitely useful too check for balancing and also tracking skills is useful. For an avn it's not necessary imo. I don't have many story related choices yet, since I'm still in the early stages. Most choices are to see which girls the player like and make their game flow smoothly without including the ones they don't like. For actual story related choices, it might be useful later, but I'd have to buy a server to receive the results and I'm not sure if I want to do that. Using polls is indeed something I intend to do more in the future, but for now, I'm focused on so many other things beside the game, hard to keep track of everything. Don't worry about the responds time :D
