I think this a perfect way to gauge the potential age / experience level of your opponent, as well. Because if you're a true fighting game oldhead, you remember a time where there either weren't more than one or two special moves, or you simply didn't know the button combinations to activate them. If you walked into an arcade and played a new fighting game for the very first time, sometimes all you had were the default punches and kicks to fall back on.
We are so spoiled nowadays, to be able to pause a game and look at the move list whenever we want. Not saying this is a bad thing - because it certainly isn't - but it's a luxury we straight-up didn't have way back when.
I've always treasured true combos - not special moves. And it was so rewarding to discover a combo on your own, whether by accident, against an opponent, or in Training Mode. Mortal Kombat 3 / Trilogy / UMK3 was infamous for its "Dial-A-Combo" systems, but gruddamn, was it ever fun to figure out how to string together a few LKs into HKs and finish with a HP or uppercut
