[quote name='Hostile']A long-term gameshare group sounds like such a bad idea to me. You would have to pay for something you don't really want a lot of times.[/quote]
I've been in a "long-term" group since July. It has gone very smoothly as far as payment arrangements go. We do the log on and give $ with your own credit card to the group account method. I think we've bought around 12 or so games so far. When we set up the group we asked for a year commitment. Given some of the stories I've heard about groups gone wrong, I think I've been very fortunate to end up, by chance, on a solid group.
I can't think of a singe game that I was really opposed to getting (although I didn't vote for everything) and everything I've wanted so far we picked up.
The problem has really been finding time to play most of those games. Sure we got The Last Guy for $1 each, but how much time can I really commit to it when I have great disc-based games (RB2, MGS4, etc.) and even other PSN games (Burnout, Wipeout) that I would rather play.
Don't get me wrong, I voted for most of those games we bought. But do I really have time to play them all? Not really. To maximize the value of the gamesharing, you really have to show restraint in what the team buys. And that is hard to do when the excitement of the discounts and buying takes over.
So my message is, if you join a group you know you're going to buy stuff, but you don't necessarily "pay for something you don't really want a lot of times." You probably end up buying a lot of stuff that sounded like a good idea at the time and you wanted, you just won't have time to play them all.
