Your Top 5 Game Gear Games
The Game Gear was one of Sega's worst systems but I still enjoyed many games on it. It's a better machine than it gets credit for. Its line-up was mostly downgraded Genesis games and shitty licensed games but it had its gems. And even downgraded Genesis games like Gunstar Heroes and Ristar were still pretty good considering the hardware.
My top 5:
1. Sonic Chaos - The best of the GG Sonics and the best portable platform game on a pre-NGPC format.
2. Aleste GG 2/Power Strike 2 - I have only played this through emulation but it's a great Compile shooter. Sega should be beat for releasing it in Japan and Europe but neglecting North America. It's a Game Gear exclusive and shouldn't be confused with another Aleste game of the same name.
3. GG Shinobi 2 - The multiple ninja thing sets the portable Shinobi games apart from the Genesis ones and makes them worthy in their own right.
4. Puyo Puyo - Puyo is great on any format and this is no exception.
5. Devilish - I haven't played the Genesis version which is likely better but I enjoyed this neat twist on Breakout-style games.
There are still a few nice-looking games I need to play a bit more like Defenders of Oasis(RPG) and Crystal Warriors(Strategy/RPG). These games might make my top 5 but I haven't played them long enough to judge.
