Just found this one, haven't played it yet but I've been meaning to try it.
Crusader of Centy for the Genesis/Mega Drive! At first look it definitely looks like a Zelda-type game, very similar to Link to the Past, complete with the overworld and the different dungeons, etc. Looks very solid in terms of gameplay and graphics. It's amazing the number of Genesis/Mega Drive games that I haven't played yet, since I grew up more with SNES.. A really deep catalog of undiscovered games for this console!
@vialli82 have you played this bro?
The best RPG on Megadrive (it's normally called "Soleil" (Sun) in French and others countries i think) is Legend of Thor and that one.
Especially Legend of Thor which is an RPG with a style of fighting beat-them-all with a sword.
But Soleil/C.O.C. is more a classic Zelda-like rpg.
Changing topic, i got also a lot of "port from poor" on my Master System and some shared on NES

about "port for poor", but ii kinda liked it.
There was something that tilted me : Sega wasn't too much about making all their games exclusives like Nintendo, perhaps some of them where created with others companies. I owned both MS and Megadrive and games got sometimes differences changing litterally the game (like Ghouls'n'ghosts and the 4-5 armors with different colors etc.)
Double Dragon, Golden Axe, Fantasy Zone, Altered Beast, Space Harrier... You can found plenty of those ports on practically every console.
Only very few games like Space Harrier or Out Run were transformed for NES (except Golden Axe) with other lookalike character but not the real name... But available in other console/PC gaming from that time.
It was probably due to the "cold war" between those two company lol.
I really believe that Double Dragon is a Sega game, but there's special sequels on NES... Mystery : i don't know if it's because the first version was made on the Arcade "System-16" machine from Sega, but owned by another company. No idea, well, we don't care it's good to have no exclusive for that jewel.
It's perhaps less beautiful than on Master System but you feel better the punch and kick + the mode B with 1VS1.
About Altered beast, on NES, looks more like a fan made port. I'll be honest, it's very bad, like if an amateur did it

the MS version wasn't really great, but that one is awful (for me) lol, nothing like the real game.
I think Shinobi was also out on NES (better on MS thought).
Otherwise many of those ports were out way before Genesis appeared, so i played all of them first on Master System.
Back to Altered beast a graphisms are good but animation looks like a "Game and Watch" haha, same as Golden Axe, with my favourite character missing : the Dwarf with an axe i always used on Arcade.
Didn't liked that version because of it, even if you could've choose the magic from one of the 3 characters.
I believe there's also "Shinobi" on NES too.
The MS version wasn't "Arcade exact", different system with a life bar on MS but longer stage and more opponents, but it was overall very close to Arcade. PC-Engine version is the closer to arcade you may found, but not especially the funniest (MS version was very fun even if it wasn't "Arcade Perfect"). No port on Genesis unfortunately... But an Hacker is working on it, i already posted it.
Well better vids than words
Altered Beast Master System :
Golden Axe Master System
Bonus Shinobi MS (own system with life bar) vs Arcade port (one touch : you lost)
