Morocco has some more free DLC in addition to the Arcade list:
Tropico 4: Voodoo
Injustice: Man of Steel Pack
Dragon Age Origins: The Stone Prisoner
Dragon Age Origins: Return to Ostagar
Mass Effect 2: Blood Dragon Armor
Alien Spidy DLC
Likewise, this didn't work for me at all on my native Russian account, and it shows as free on my migrated account, but requests payment, if anyone's still trying out there
Assassin's Creed 3
$23.99 at Play-Asia DEAD
and free shipping over $25
(find a good dollar filler to share?)
Appears to be NTSC-U with no region protection
Only for 360 version, appears to be best price ever advertised
