Earthbound (Mother 2) was released for the first time in my country just last year (on Wii U VC), so I didn't grow up with it like a lot of other people.
Anyway, I picked it up when it was made avaliable, but was a little disappointed. I was a expecting something mind blowing and hilarious like everyone described, but all I really got was a really slow paced RPG and not many laughs. Maybe it picks up, but I don't have the patience for it.
Haven't played Mother or Mother 3 either, as you'd probably expect.
