Games that make getting a Genesis worthwhile?

[Nightstar699]

I got rid of my Genesis long ago, but Marvel Land is a pretty good underrated game for it.

Dragon's Fury, a port of the PCE's Devil's Crash. And Thunder Force IV is imo the best part of the series. Impressive graphics and a pumping FM-Metal soundtrack.
Turtles- The Hyperstone Heist is great too. Not as fancy as Turtles IV, but with more arcady music

I'll second (or third, or whatever) Gunstar Heroes, Strider, MUSHA (where my username came from), Castlevania Bloodlines, Golden Axe, Burning Force, The Revenge of Shinobi, Shinobi III, Bio Hazard Battle, Alien Storm and the Thunderforce games. A few others definitely worth looking into are:

Mystic Defender
Shadow Dancer: The Secret of Shinobi
Splatterhouse 2
Splatterhouse 3
Valis III
Gaiares
Ghouls 'N Ghosts
Truxton
Target Earth
Castle of Illusion starring Mickey Mouse
ESWAT: City Under Siege
Phelios
Batman (based on the '89 movie)
