I'll raise my hand up, here & now admit that I will always look for a sealed copy of a game over an unsealed one, money permitting of course. I do this because I like to have the game in perfect condition, however, all my games are opened & played. They'll never sit on a shelf still sealed.
If it's an older game that has to be got from eBay, then I'll bide my time & wait for a sealed copy or at the very least a copy in good condition. If it's a game that I really, really want asap, then I'll get whatever's going, as long as it's complete.
When I picked up my GC on PAL launch day, all my games were sealed except for SMB, which had obviously been played before, so days later I took it back & got a sealed version.
Also when I picked up my PSP, I asked for a sealed copy of Metal Gear Ac!d, but was told that none of the copies were sealed, however I knew that my copy was brand new just by looking at it. Therefore, I was still a happy bunny.
I very rarely buy from retail stores nowadays (due to the daft prices) but when I do, I'll always insist on getting a factory sealed copy of the game. If it's an older game, I'll get the shop assistant to trawl through the stockroom until he finds one !
If you really do have to have sealed games all the time, then surely the answer is to preorder online the second the game comes out. That way it'll never be pre played.
So, overall, it is strange that one company doesn't seal their PAL games, but I'm certainly not going to get hot & bothered under the collar.
Just a further note GP. Please don't start this topic over at Games tm. I don't think the forum & it's members could stand it...
