Thanks for all the replies! It's good to know I'm not alone in my endeavor. I've considered such things as security cameras and building a secret room. I've had almost my entire collection at the time, about 150+ titles stolen from me before, and it was a terrible feeling. Luckily, I had kept a catalog of every title and photographs of the whole collection. This was back in the Gamecrazy days, and I had some friends who worked there, as well as in our local Video Game Exchange. I gave them the list and the story, and they said they'd keep an eye out. Sure as shit, two days later, about 30 or so games popped up between both stores. The best part is that they require some personal information when you trade in games, be it for cash OR credit. The guy gave them a fake name, BUT GAVE HIS REAL PHONE NUMBER AND ADDRESS. Cops found him, returned another 50 or so games to me that they found (COVERED in fingerprinting dust, but whatever.), also reported that they found a sawed off shotgun as well as a ton of other stolen shit in his house. They connected him to over a dozen other burglaries in the area. I didn't get my PS3 or about 70 games back, but luckily my parents (I was 17 at the time) had property insurance, so I repurchased most of them.
I'm glad I've found this community. I really feel like I've found some kindred spirits here. Someday I'll actually post my collection lol...
