I'm sorry but this discussion has been done to death, and then someone dug it up, 'mishandled' it and buried it again.
Retro games are harder because they were unforgiving due to the nature of arcades. This having evolved over time meant that games don't need to eat all those tasty nickels or whatever you American people call your money. Games were already a lot easier in the PS / N64 / dreamcast and whatnot era.
Oh, if you take casual games (see 90% of wii games) into this discussion, then really they can't even be classed as easy as any form of challenge is non-existent.
