I sold my GG years ago but still have some games left. Here's the list: 4 loose Tectoy carts - Sonic the Hedgehog, GP Mônaco (Super Monaco GP), Castle of Illusion and G-Loc 2 US carts with the protective case - Columns and Crystal Warriors 2 US carts with the protective case and manual - Sonic 2 and Sonic Triple Trouble 2 US carts complete with box, protective case, manual (missing the internal inner tray) - Sonic Chaos and X-Men Pictures: http://imgur.com/a/fG9o2 Crystal Warriors is a rare title, Sonic Triple Trouble is uncommon, while Sonic Chaos and X-Men have some value for being complete. Still, these are GameGear games. Since not much people collect them, i honestly have no idea how valuable or not they are. That's why i prefer trading. I have interest on Gran Turismo itens, but also PS1 and PS3 games / related stuff.
