Correct on both
[quote name='Rodimus']#2 is Eternal Champions, probably the Genesis version.
I'm guessing this is an obscure fighting game trend. #4 kinda reminds me of those X-Men fighting games on the PS1, but I know that's wrong.[/QUOTE]
Actually, you know what, I will give it to you. 2 is Eternal Champions: Challenge from the Dark Side for the Sega CD, but it is based on the Eternal Champions engine and really just a title update, not a sequel.
No luck on 4 though
