The point is: Go buy a Gameboy system. This system made Tetris, Wario, Kirby
 and a few others the super stars of today. This system boasts FOUR
 (ORIGINAL, not remixes.) Final Fantasy games (More than any other system.),
 Two Ultima Games, 5 Mega Man games, 4 Bomberman games in Japan, versions of
 all three Donkey Kong Country games, fighting games you won't find together
 on any other system, 4 Mortal Kombat series games, The King James and NIV
 Bibles (From Wisedom Tree.), Game Genie capatability on all system
 variations (It makes the Gameboy Pocket top-heavy though.), bits of FMV
 (Like at the end of "Link's Awakening", ZERO load time, over 450 quality
 games to choose from, over twenty good RPGs, 4 Castlevania games, several
 new game concepts (Like Wario Land 2's "No die" premise.), a printer and
 camera, several good racing games, Turok, James Bond, two Contra Games, 
 2 Paridous games, 3 Adventure Island games, 2 Ultima series games,
 several great puzzle games, way too many Mario/Wario & Kirby series games,
 etc.
