I liked Metal Slug 3 the most. However, I think that's the only game on that list that I've played... Not much of a fighting game fan
MS3 is too long in my opinion. It just gives me the impression that it was impossible to 1cc it, the other Metal Slugs are shorter and fairer I think.
I was torn between MS3 and Garou. Went with MS3. Samurai Shodown III is also great, i like it better than IV.
Honestly, I think MS3 is too long. It has lots of great ideas and all that, but I think they'd have done better in splitting it up into two games. MS1 is still my favourite btw, shortly before MSX.
Fatal Fury/Real Bout Special for me. First game I ever played on the Neo Geo, I never got over it :icon_bigg
I chose other, since SNK has made a load of great games over the years. And they are still smashing today.
