These are all Genesis suggestions:

• Rocket Knight Adventures
• Sparkster
• Shinobi III
• Teenage Mutant Ninja Turtles: The Hyperstone Heist
• Rock n’ Roll Racing
• Thunder Force III
• Lightening Force: Quest for the Darkstar (aka Thunder Force IV)
• Dynamite Headdy
• Ranger X
• Gaiares
• Gargoyles
• Eliminate Down
• Alien Soldier
• Chakaan
• Dragon’s Fury
• Sonic Spinball (if you like pinball games, you might like this)

Wonder Boy in Monster World! Fuck! I loved that game so much!

It’s like a Zeldavania RPG, is the best I could describe it. Can’t remember the story for shit, but I played the balls off of that game. A bit grindy, but that is part of the appeal.

If you’d like to try general action games as well:

• Gunstar Heroes
• Strider
• Final Fight CD
• Contra Hard Corps
• Streets of Rage 1-2

Also try Snatcher on Sega CD.

Other thoughts:

1. I’ll just note that Phantasy Star III, even if it is older-school grindy at times, is a really interesting take on multi-generational epic storytelling. I like it more than Phantasy Star IV.
2. Night Trap on the Sega CD is interesting to play around with for an hour just to see what FMV games in the 90s meant, for some interesting bad late 80s/early 90s acting, and to remember that was all it took to cause a national panic for awhile.

To add to others’ suggestions:

• Road Rash 1-3
• Micro Machines 2
• Lotus Turbo Challenge 1 & 2
• Truxton
• Bonanza Bros
• Ristar
• Aladdin
• Gunstar Heroes

how about Sega Saturn? Panzer Dragoon Saga is one of the best JRPGs ever. Don’t mistake it for Panzer Dragoon 1 and 2, those are rail shooters and you don’t need to play them. Also Dreamcast has some really good RPGs, I love Grandia 2

Desert, jungle and urban strike

If you leave Saturn and Dreamcast off your list then you’re really missing out.

The uhhhh Shinobi games. Mega Turrican. Chakan, if you enjoy a challenge. Edit: Streets of Rage

A couple interesting ones that I remember:

• Haunting starring polterguy
• Jurassic Park
• Aladdin
• Ghostbusters
• Castle of illusion starring Mickey mouse
• Road Rash 2 (maybe it doesn’t hold up these days)

Sports Games

Well, I have bad news for you about a significant fraction of the Genesis’ library…

Some other decent Genesis/Megadrive titles I can think of off the top of my head: Gunstar Heroes, Vectorman, Megaman: The Wily Wars, Zero Wing (for the memes), Aladdin (which was a completely different and vastly superior game to its SNES coutnerpart), Blaster Master 2, Contra: Hard Corps, Ecco the Dolphin and its sequels, Jurassic Park, and probably loads of others I’m forgetting.

The Saturn is notable for having Radiant Silvergun locked to it, in Japan only no less, and I don’t think that title was ported or rereleased at all until the XBox 360 version. It’s the precursor to Ikaruga, which is itself on the Dreamcast.

If you’re into shmups, the Dreamcast is kind of a holy grail. It also has the first two Shenmue games on it.

Alas basically everything on the Sega CD is crap with few exceptions. I will probably surprise my readership by mentioning that I think Sonic CD is not one of them, as its easily the weakest of the classic Sonic titles. It has some cult favorites that are so bad they’re good, though, infamously including Night Trap, Time Gal, Corpse Killer, Sewer Shark, etc. For games on it that don’t suck, don’t forget that the first two Lunar games originated there, there’s Popful Mail, Keio Flying Squadron, Snatcher, etc.

The 32X is an interesting novelty but I’m not certain there’s a single compelling title in the entire library. Which, admittedly, is only something like 30 games.

adding some i always found unique or interesting

• Flashback
• Cyborg Justice
• Ecco the Dolphin
• James Pond
• road rash
• Skitchin’
• General Chaos
• streets of rage (i liked 2 the most)
• Combat Cars
• Bonanza brothers
• World of illusion
• Quackshot
• Sunset Riders
• Action Fighter (i swear this isn’t a fighting game, it’s about evolving motor vehicles)

Definitely Shining Force 2. 1 is more linear, and while It plays very similar it kind of stinks you lack freedom to roam around the world wherever you want.

Vectorman is a great platformer.

This is the first “What should I play on early Sega?” thread that already has almost all my favourites. In fact, many of them are in OP’s list. But to reiterate some added by other commenters:

• The “Strike” games (Jungle, Desert, and Urban)
• Flashback (I agree that the MegaCD version is the best single version, but the fan community has been building a Frankenstein’s monster from the best parts of every version; I forgot the name of the project)
• Wonder Boy III: The Dragon’s Trap (SMS)
• Wonderboy in Monster World (MD)
• Quackshot (MD)
• Rock ‘n’ Roll Racing (MD)
• Sunset Riders (MD)

I don’t think anyone’s yet mentioned:

• The Immortal (MD)
• Golden Axe Warrior (SMS)
• Arcus Odyssey (MD)
• The Lost Vikings (MD, although I played the PC version back in the day)
• Micro Machines (MD)
• Crack Down (MD)
• Gain Ground (MD)
• Alien 3 (MD)
• Addams Family Values (MD)
• Monster World IV (MD, although I haven’t actually played it yet)

And a few more that I’m fond of, but I either can’t remember them clearly (other than that I enjoyed them at the time), or I’m aware that I can’t separate fact from nostalgia, so YMMV:

• Sword of Vermilion (MD)
• Light Crusader (MD)
• Robocop vs Terminator (MD)
• Predator 2 (MD)
• Cosmic Spacehead (MD)
• D&D Warriors of the Eternal Sun (MD)
• Atomic Runner (MD)
• Techno Cop (MD)

An honourable mention to Cadash (MD), which is a solid attempt at a port but sadly can’t really hold a candle to the arcade original.
