Voted for NGC98 but I'd vote for Super Sidekicks 3 in a heartbeat if you put it on there. Every time I play it against someone we get all crazy, yelling and trash-talking like nuts. Doesn't happen for Magical Drop, KOF, Turf Masters, etc. but Super Sidekicks 3 gets the adrenaline up. Is the presentation for 3 the same as the others, with the cutscenes and all that?
Note that I've only played SSK3 and NGC98 (and 98 was one time at an arcade).
