One of the problems with the older generation of games, especially those less powerful handhelds, is that most of them are a one-time thing. Few have any replay value beyond looking for items or areas you may have previously missed. And even rarer are expansions and DLCs. Fortunately, the gaming community is not lacking in hackers and modders who are more than happy to extend the fun. Like this new Newer Super Mario Bros. DS that adds content to an older portable title.
