Years ago I inherited my wife's family's Game Gear. After a recap, and replacing the backlight, I started tracking down games to play on it. It's been great exploring a whole library of games that I skipped out on as a kid! (I was a Nintendo kid) Now I have a nice little library of carts to play on this beast of a 90's handheld.
Thank goodness for modern electronics!
With a LED backlight, the battery life of this almost triples! And rechargeable batteries are way better than what they were in the 90s.
I didn't have any Sega System as a kid, so all the Sega franchises have been brand new to me the last few years - there's some really great stuff in there!
