Its actually pretty funny you should bring this up. I personally dislike GH games b/c they stick out like a sore thumb on my wall of games.
One such example that ALWAYS bugged the hell out of me was Castlevania: SOTN for PS1.
Ironically enough, I was at Gamecrazy about a month ago and I saw the non-GH version for $15. I didn't have the cash at the time (I was actually trying to trade stuff in) so I reluctantly passed on buying it. Just this past wednesday, I finally got some money again and I decided to stop in and see if they still had the game. After about 10 mins of digging through the PS1 game wall, I FOUND IT. I took it up to the counter to buy and the guy started searching for the disc. Turns out someone else sold the disc w/o the case. I asked if I could just buy the case and he said I could just take it!
So I got home, took the disc from my GH case and put it in the new non-GH case!
There can be miracles, IF YOU BELIEVE....
lol, sorry, it was on the radio.
