It's just a bunch of fun games to play - and remember, as I wrote, I get only knee deep into lots of them because my lack of skill. SO you could easily argue this is a list more for novices. Skilled/expert players would have a different opinion based on depth of play.
The other point I thought I should address is that the reason I put both scrolling beat-'em-ups and Vs. fighting together is that I use the Hyperspin front end and they are both categorized and thrown together in the "Fighting" Genre - so I kept them together that way in this list. Certainly I agree they are apples and oranges. It would be difficult to directly compare the two types, the ratings are certainly relative to each sub-genre. In other words, when scoring, I was definitely comparing the beat-em-ups to other beat-em-ups, NOT to the Vs games.
Graphically speaking - there is certainly large variance in some of the games on the list. You really shouldn't read it as "best" graphics as much as "most enjoyable". That's why some games like Punisher and Super Gem Fighter scored high, they just cracked me up.
If I'm gonna do a blog about games, I'm gonna have to express my opinion and I know folks are gonna disagree. Like others have said, it's just my opinion (RIGHT NOW!) and I'm glad it can spark the debate.
