Ideally I'd like a list of games that would have been great in the arcades but were only ever a console game.  I am adding a small smattering of console games to my emulation machine , and I want to keep the games in the same spirit. I get that this is subjective but I'd like to see what you guys/gals come up with. Not trying to add hundreds of games either 
 
 Best example I can think of is Weaponlord on SNES/Genesis. 
my "rules":
Not a console port of an arcade game or an arcade collection (ie no midway hits, tmnt hyperstone, etc)
  - PC-10 games are exempt
  - Games that make the games playable on standard controls, like Marble Madness - NES are exempt
  - Games that share the name with an arcade game but are vastly different are exempt
Works with "standard" arcade controls, no trackballs ,spinners, flight sticks, analog controls , etc
Games that are good, not just ones that could have been an arcade game (ie don't suggest Zoop pls)
If there is a game that's multi-platform, please suggest the "better" version but also what other platforms its on.
If there's multiple in a series, just list the best one ( ie Streets of Rage 3) unless more than 1 is worth having on the list
my list so far, subject to change:
Clayfighter 2 - SNES 
Comix Zone - Genesis 
Eternal Champions - Sega CD (also on Genesis)
Fighters Megamix - Saturn 
Final Fight Mini Mix - NES 
Final Fight 2 - SNES
Gradius V - PS2
Ice Hockey - NES 
Pipemania - NES 
R-Type III - SNES 
River City Ransom - NES 
Rock n' Roll Racing - SNES (also on Genesis)
Shinobi III - Genesis
Sonic 3 w/knuckles - Genesis 
Streets of Rage 3 / Burning Knuckle 3 - Genesis
Super Double Dragon - SNES 
Super Mario 3 - NES
Tecmo Bowl - NES (its only the same in name to the arcade game)
Weaponlord - Genesis (also on SNES)
Zombies Ate My Neighbors - Genesis (also on SNES)
