It's an amazing early Genesis game that is a must play. I run through it every year.
Edit: Metal Jesus Sega Genesis 11 hidden gems. Watch
here
Ex-Mutants
Jewel Master
Blades of Vengeance
Final Zone
Mazin Saga Mutant Fighter
Sub-Terrania
Mystical Fighter
Atomic Runner
Phantom 2040
Wardner
Crue Ball
CGR Undertow ripped Crue Ball but I thinks it's great.
Also Sunday I'll close the voting for March so vote here if you haven't
Of those games, Sub-Terrania and Blades of Vengeance are great, A-grade classics and absolutely belong on any underrated Genesis games list. Get both of them, they're fantastic! Atomic Runner is also pretty good and well worth a try. And Ex-Mutants, Wardner and Jewel Master are decently fun games which may be worth a look if you like tough platformers. So yeah, decent mentions for those. And unlike some of his 'hidden gems' lists, those games probably are all actually not well-known games.
Mazin Fighter, however, is awful. The beat 'em up side of the game is okay if below-average stuff, but the 1-on-1 fights are absolutely terrible and ruin the game! That's not a good game.
I don't have Crue Ball, Mystical Fighter, or Final Zone, so I can't say much about those. As for Phantom 2040, I've played it for SNES and it seems average.
So what would I put in a list like this? Hmm...
Sub-Terrania
Adventures of Batman & Robin
Blades of Vengeance
Outrun 2019
Hardball III
Rolling Thunder 2
Universal Soldier
Technoclash
Atomic Runner
And also Mega Turrican if I can get away with calling it under-rated, but that's a bit sketchy I guess.
Vectorman, Shadow Dancer, and Ranger-X are other somewhat popular games I really like and think should rank higher in best-of Genesis lists than they already do.
