I owned many systems throughout the years though i never really developed a liking to an extent for some older retro systems like some others have. However i always loved my gameboy color/gameboy advance its probably the 2 main systems that i gathered play time more than any other console or handheld i ever owned. When the gameboy advance launches and even some years after it i still found myself playing it often even though i had things like an n64, ps2, gamecube etc.. When the gameboy advance sp launched i though it was a fantastic device considering i always had to play a gba in daylight or with that worm light to see properly. However i never really liked the gba sp because of its size the regular gba was just more comfortable to hold and play for me. When the psp came out it was also a big hit for me specially when the option to play older retro games and gba was possible as well. What handheld system has been your favorite/most liked?
