Sorry, the rabid MH fanbase wasn't 400k+ in the US alone. Looking at previous installments it was significantly less than half that. Advertising and Nintendo diehards are what drove it above the usual western MH base and it went on to outsell basically every other major Capcom game that wasn't RE, DR or SF from 2010 on. Tri was far from a failure in the west.Because of he kind of game it is?
Online co-op hunting game would have killed on those systems because they didnt have the infrastructure hangups the wii had and a more active online player base.
People like to rag on Resident Evil 5 but the online co-op carried it.
Tri was great but you didnt have the same massive online crowd and hardcore base attached the system. It sold well purely to the rabid MH fanbase and even then we complained about its terrible setup for online play.
How did PSU sell? How did LP2 sell? It's not as if similar games hadn't failed to take hold in the west before on those platforms. The kind of game MH is has never really been a hit on PS or Xbox overseas so I'm confused where this assumption Tri automatically would've done even better (without Nintendo's promotional push) comes from exactly?
