I have a friend, and she owns a Game Gear but only like one game. I want to get her some games for the Game Gear, but I don't know which ones to get (I was never a huge Sega person, I only got a Dreamcast after Gamestop was selling them for $10 each in like 2003/2004). Which are some good games for the Game Gear? And is there a rechargeable battery kit for the Game Gear? Thanks for the help guys!
