No matter how obscure a game is I can immediately find fans of the game to talk about it with. I feared No one would have Transformers Prime on this site but I just went to Miiverse and a bustling community was talking about graphics, bosses and end levels. It's just awesome not feeling like the only person in the world who bought a game.
Not to mention the fact that if there was an online multiplayer aspect on an obscure game I won't have to forgo it because I couldn't find anyone since we're all in the community I can add friends and battle against them. I have no doubt 720 will have this too.
