Capcom Europe objects to sequential order
As "Chompman" explains, "There's no spoilers in Apollo Justice that would stop you enjoying Trials and Tribulations if you played it afterwards though." Well, that makes it okay. European gamers are certainly used to later game releases by now, but out of sequence? That's a new and special way to irritate a fanbase.
Oh, by the way, the U.S. version of Trials and Tribulations is $18.99 at Amazon.
