Oh Beat 'Em Ups...

Going to make a top 10 list of beat 'em ups since I've played a fair share of them. It's definitely one of the most repetitive genres in videogames, but it would be nice if there were more of them nowadays in 2D.
Top 10(in order)
1. Teenage Mutant Ninja Turtles: Turtles in Time(dev. Konami)[Arcade]
It's not exactly deep, but it's still one of the most immediate and fun games in the genre. It might be the nostalgia talking, but I doubt anybody wouldn't include this on his/her list.
2. Alien vs. Predator(dev. Capcom)[Arcade]
I just discovered this game recently, but man, it's a great one. Thank God, they made special not take any of your life away, which just seemed lazy and made things unnecessarily hard in their other beat 'em ups.
3. Comix Zone(dev. Sega)[Sega Genesis]
While I'm not sure if it's technically a beat 'em up since it's only on one plane, it pretty much has everything else found in the genre like screens where you can't progress unless all the enemies are taken care of. It's one of the most difficult games for the Genesis especially in it's original state with no save system, but it's one of the most rewarding.
4. Captain Commando(dev. Capcom)[Arcade]
Capcom is the king when it comes to beat 'em ups and fighting games so it's not exactly a surprise to find them on my list more than once. Babies, mummies, ninjas, and robots... what's not to love?
5. Streets of Rage(dev. Sega)[Sega Genesis]
Lots of people say Streets of Rage 2 is the best, but I'm not a huge fan of the whole special move taking up life and I enjoyed the screen clearing special in this. It's unquestionable that Street of Rage 2 has better graphics, but this one has a better and more memorable soundtrack. It's fairly standard in terms of beat 'em ups, but it's still one of the best.
6. Battletoads(dev. Rare)
The other beat 'em up with amphibians. It's considered one of the hardest games on the NES and it's also one of the best.
7. Rollergames(dev. Ultra aka Konami)[NES]
It might not be a beat 'em up because of the ability to move up and down, but if the whole game revolves on beating the shit out of other people with your fists and feet then I would classify it as a beat 'em up. Sort of a guilty pleasure just because it's a damn beat 'em up on rollerskates, but I still enjoy it immensely.
8. Vendetta(dev. Konami)[Arcade]
It essentially has recreations of Mr. T and Hulk Hogan. Enough said.
9. Golden Axe(dev. Sega)[Sega Genesis]
It's sort of required to put this on a beat 'em up list especially considering it's one of the more original games in the genre. Sure, there were other medieval-themed beat 'em ups, but this remains the most well-known with good reason. It's kind of murky territory whether this should be classified as hack n slash instead of beat 'em up, but whatever.
10. Cadillacs and Dinosaurs(dev. Capcom)[Arcade]
It has possibly one of the coolest titles ever. It's pretty bizarre and awesome at the same time since you fight a lot of dinosaurs along with people and even dinosaur people. Also when you continue, you start out with a bazooka. It's definitely not in the league of an Alien vs. Predator, but it still remains enjoyable.

Yes, I didn't put Final Fight on the list because it's dated and there's simply better beat 'em ups that came after it. If this was a list about historical importance, it'd probably be on the top of it, but it's not so it's not even on it.
