Battlefield: Bad Company Gold Edition - slipcase version.
I've had my bunch of chances to get the steelbook version of this game in factory sealed condition but for some particular reason I didn't feel like buying it - the fact that I don't like steelbooks was reason enough for me to hold back when I had the chance. I was actually more focused on getting the slipcase version that came out in region 3 countries (Asia I believe) and I finally managed to find a good deal locally for a mint condition copy, not sealed though. I was blad that I got it. Now I need to find a copy of the Limited Edition of the second game. And now that I think about it, I'm still missing the older games, the ones before bad company.
