In my opinion, within that era the WHOLE:
SNK experience is- KoF 2K2 (consensus best of that era), SS4, LB2
Capcom experience is- SFZ3, SF3:3S, VS, MVC2, PJ, PS2, Techromancer...
and if you REALLLLY wanna be a stickler and only use one game with "street fighter elements", then just go SF3:3S and then play VS, PS2 and Techromancer.
But you are asking us to know your opinions on what constitutes "an experience of the developer/publisher" and then prove to you what is "essential" for that experience, and that is going to be different for every person.... So different in fact, that it will end up just being a bunch of people trying to post games from those companies that no one has posted yet, and the "experience" just becomes a title from every single franchise in that timeline. So, there you have it
