There's now 700 reviews on Amazon. Do you really think the game's 2-star rating is just the result of bitter PlayStation owners? We are in 2014, MH on Nintendo isn't a shocker.
You can look at the ratings for the other Nintendo entries:
Tri,
Tri G,
4. MH4G's worse than all of those.
Obviously a group of 700 people isn't exactly major when you're dealing with a game that sells millions, but it'll be interesting to see how things play out for future hunting expansions. Are consumers starting to burnout with these annual releases? Will append versions become more common place? Will Capcom be too busy counting their money to care?
