2 - too difficult or complicated
3 - too easy
Who are you defining 'too difficult/complicated' and 'too easy' for? I thought FFX was amazingly easy (even the 'dreaded' Seymour fight) and simple, but my ex-girlfriend thought it was a difficult and complex game.
Some people think Grandia III is pretty tough - I think it's simply uneven.
I'd like to see more variable difficulty games in regards to the encounters, myself.
