As someone who owns most of the LE releases for the Xbox 1 I can say that the 360's LEs on a whole are total crap by comparison... Halo 2, SCDA, Doom 3, Getting up ... all came in metal cases... These days it seems an extra booklet and a slip cover constitutes "LE"
I will say that there have been a few nice ones though, Prey, GoW Oblivion and Bioshock were all well worth the LE price tag... PDZ was a decent LE though it's wide spread production, much like Halo 2 caused it to lose it's appeal.
Europe has had fewer LE releases but I think they've been much better games and much better quality... LE releases like Dead Rising in a nice metal case and Forza in tin similar to GoW would have been f-ing awesome.
... I was just looking up release dates on EBGames.com and noticed that next week stranglehold comes out and they're releasing an LE version... yet another slip cover with a DVD for an extra $10

and of course I'll buy it because I'm addicted. though I suppose it wont be too bad because I've already got H3 paid for and after that the only 2 LE games this year are Jericho and Assassin's Creed
I may just play the gamble on Stranglehold and see if the LEs stick around for a while and drop in price over time.
