Had one of the most expansive game libraries of all time, as it could play most other Game Boy and Game Boy Color games. Reasons to buy this system or its successor, the GBA SP, include but are not limited to: Castlevania COTM, most of the Final Fantasy games, the Pokemon series, and the Legend of Zelda series.
Those unlucky few who fail to realize that the SNES lives on in the GBA and later the DS and DS Lite are doomed to waste money on games and systems that focus so much on graphics over gameplay that they'll be playing episodes of Friends while the true gamers like us will be playing the games that made and continue to make history.
person2: you know it!
(Game Boy Advance: yes, yes, succumb to my infinitely gargantuan library that makes the collective library of PS3 and Xbox 360 look like a school library selection of useful books. Alas, my library is only rivaled by that of my newer relatives, the DS and Wii!)
