When I got my Wii I though that was the case, SMG is tons of fun but really is pretty easy but I thought it might have had something to do with the fact that when I was playing SMB, SMB2 and SMB3 I was 9-10 years old and didn't have the dexterity or mental capacity that I have now so those games seemed easier.
Well I downloaded SMB3 for NES and MAN is it ever a lot harder than SMG. You have to finish an entire level without dying to be able to save to the next level and you get so few 1ups that it makes it quite a lot more challenging.
Other games like MOH H2 are also incredibly easy, even SSBB on intense is a lot easier to get through than SMB3.
Anyone else have the same experience?
