My take on this whole thread is this:
If I have a choice and big screen in front of me I would rather use a digital joystick if I can. If given the choice of one or two buttons I would go with two and leave up mapped to jump at the same time. If I have to use a joypad especially on a handheld console then I also want a button mapped to jump. I also like the mario games, I don't think they are gods gift to platform gamers though.
Bubble Bobble and the rest of taito's coin-ops are gods gift to platformers.
Those are enjoyable on nearly every console, arcade machine and home computer unless the conversion guys totally botched it up.
I do really love Super Mario Land on the monochrome gameboy though, imo they just got everything right in that game. The rest of the mario games for the orig gameboy are pretty crappy though.
THIS IS ALL JUST MY OPINION AND IS NO MORE OR LESS VALID THAN ANYONE ELSE'S OPINION.
