Game Stores in Michigan? Well, when I was living in Midland I'd go to Game On and Game Traders. I've gotten good finds at both. But Game On did seem slightly more organized. I also think they had a better selection. I found good prices at both.
I know our one friend opened a new store in Bay City called 1-Up Games. But I haven't had a chance to swing in and check it out yet. Maybe I'll do that after work sometime this week.
In Saginaw there is Video Games Plus, some folks think his prices are a little out there, but he does have a lot of stock. I've gotten some good finds there as well.
