There's actually a bunch of stuff I would love to buy, but would never pay much for given how little Avatar's get used right now.
Avatar's Need:
1.) More use in more games. What the heck was MS thinking in not making Arcade actually have direct Avatar control? If Avatars had more usage, I wouldn't mind paying the prices Avatar clothing and items currently cost.
Or
2.) Cheaper prices and more free stuff. Because I can't use my Avatar for much I don't feel any incentive to spend much money on it.. but there is some pretty cool stuff I would buy even with the little use it would get if only it were cheaper.
