I was driving around today (for work) and I drove by a place called "Retro Games Plus". I did a quick google search once I reached my destination and found one closer to my home. I stopped in and saw a ton of console games mostly old, some new. A lot of old PC games (Delta Force by NovaLogic), many in jewel cases. I didn't have time to look through them all but I'll definitely stop in there again. They also had Atari games, Lego and general game merchandise (like a Fallout PipBoy).
There is also a Game Exchange in my town but I never stopped in. I'll see if I could stop there on lunch tomorrow.
