Oh man, there are so, so many.
The one that I have the fondest memories of and the store where I bought and traded most of my video games growing up was a Software Etc store inside a mall that is no longer around either. I bought 75% of my N64, PS1, Gameboy, GBA, Dreamcast, PS2, and Gamecube games from there until it closed down in 2005. I spent a lot of time there with friends just window shopping and looking around as well. Just typing this is making me feel heavily sentimental about it.
We have a string of video game stores in Colorado that I don't believe existed elsewhere else called Game Force. Growing up there were probably a dozen different Game Force locations around the state and they were all individually franchised, which to my understanding all the locations were owned by five different people who owned different locations. There was one up the street from my high school that I used to walk to on my off hours and I purchased many games from there as well, including my first older console that I bought to get into older video games and game collecting, the Sega Saturn. There was also one in a more affluent suburban area near where I grew up that I really enjoyed going to. Both of these stores have been gone for over a decade now, and all the other Game Force locations are gone except three. Sadly just three or four years ago there was double that, which makes me worry about the future of these independently owned stores.
And finally, like you, I had a Game Crazy near my house from like 2001 to 2005 that was attached to a Hollywood Video store. I made a point to go in there every time I went to rent something, however I can't remember buying a ton of games from them, mostly because I was still buying from Software Etc and an EBX which eventually evolved into a Gamestop and got relocated down the street. Still, it was a cool place that I remember fondly and wish it was still around.
An honorable mention was an Incredible Universe store that was open very, very briefly near where I lived, but it was literally there for a year before it went out of business. I remember it being so cool and awesome even though I think I only went there twice. I wish I was old enough to remember it better and to have shopped there more.
