Finally got my order from Games Express. The games looked pretty beat up, but that was because the shrinkwrap was all frayed and scratched up. After taking off the shrink, the cases and everything looked good. A few case cracks here and there, but nothing major considering the age of the stuff.
SimEarth was the worse of the bunch. There was some tape or something sticky on the side and somehow melted to the shrinkwrap which left a yellow nasty goo on the case. Should be able to clean it off with goo gone or something... or just replace the case entirely.
Overall, not disappointed!
