World e+ looks so cool it pisses me off that Nintendo chose to release it in such an obscure format that most people justifiably wanted nothing to do with. What a waste.
Maybe they'll be nice and some time release them on the VC. Or release a Mario Rarities game on the DS that includes all these levels and any of the unique content in Vs. Super Mario Bros, Super Mario Bros. Special and, hell, the Mario related Game & Watch games. They could also include Japan-only stuff like Wrecking Crew '98 and Mario Excitebike. One could probably easily scrap together enough obscure Mario content to charge full price for it.
