My favourite SEGA games:
1) Sonic the Hedgehog: it is pretty difficult game with bright colors and memorable music.
2) Comix Zone: an action game with very good graphics.
3) Streets of Rage: one of the best fighting games for SEGA.
4) Jungle Strike: a helicopter-based shooter with very interesting gameplay.
5) Golden Age II: a fighting with swords and adventures in ancient times, has exceptionally good soundtracks.
6) Road Rash 3: a racing on motorcycles, has interesting gameplay and memorable music.
7) Power Monger: a medieval times strategy; gameplay is very primitive, graphics are ugly but the game was nevertheless interesting because there was no other strategies of such a type on SEGA.
8) Dune: a great and popular strategy in other planet in future; has decent graphics and interesting gameplay but is too easy, so even a not very skillful player can kill all enemies and conquer the planet.
9) Master of Weapon: a cosmic shooter with decent graphics and amazing soundtracks.
10) Mortal Kombat III: the best fighting on SEGA.
