No it's not! The first one is a platformer, but the second has several different game styles, including those topdown bumper cars levels, etc. It's not just more of the same. (This game was from late '92 in Japan, and early '93 in the US.)
Sure, but it's interesting that Konami was still making NES beat 'em ups in early 1993. The other Konami games from early 1993 include F1 Sensation (JP only, average-looking racing game), Bio-Miracle Bokutte Upa (JP only, good platformer), and Zen: Intergalactic Ninja (part isometric platform-action, part platformer -- unique mix!).What is Batman Returns? A simplistic beat 'em up just like Mighty Final Fight and other NES brawlers.
Yeah, this one definitely is interesting -- TMNT Tournament Fighters released in spring '94, a full year after Konami's previous NES game -- they released their last '93 titles in April, then nothing until Tournament Fighters the next spring. And it's somewhat unique for the platform too, of course; not too many traditional fighting games on the NES! But looking at those '93 games, I would say that Zen is also unique, and Bokutte Upa and Batman Returns are quality games for sure. Konami put effort in their NES games until the end. Well, mostly; Contra Force was another title from later in '92, along with Tiny Toon Adventures 2...Tournament Fighters was rather surprising to see though, as the NES had no history of fighting games with very few exceptions like Joy Mech Fight.
