Now, RANK ORDER ASIDE, I just can't question the list. Like everyone else, I did at first but now I've looked it over a bit further. Never played the Batman game so I won't bash it, but I'm sure it must be the weakest game on here (after all, that's why it's #10). Sure... you could replace Golden Axe with something I guess.... but you can't fault the choice of it. After that the rest are untouchable-- though Simpsons and TMNT4 might belong further down (no doubt though, neither of those games has any business being as good as they turned out; TMNT especially is an excellent game).
So seriously, tell me what game DEFINITELY belongs off that list (besides the repeatedly mentioned Batman game, which half those people have probably never played anyways)? And what game DEFINITELY deserves replacing it? I don't know that it's that easy to make say anything for sure. I mean, personally I think Guardian Heroes is tops (very few here probably played that; it's a Saturn game worth around $60 off eBay), but I can't fault a collective group of people for putting Final Fight and Double Dragon above it.
Let's face what the real problem here is-- the beat 'em up genre was just never that great to begin with. You're all looking through those 10 games there thinking "man, some of those are just average games; not Top 10s." But hey, it's not the lists fault.... the genre was lots of fun when only a few games were around, but then it got completely overdone. The reality is that the gameplay just offers very little depth, so you only need to play a few games in the genre before you realize its repetitiveness. Hence why the genre is now dead-- Guardian Heroes came out in like 1996/1997 area and it's the last great game of the genre; so I think that tells you exactly where the problem lies. You can only list about 7 or 8 games before you start leaving "great game" territory and get into "mediocre game" territory. Not many other genres have that same problem.
