Even though it was only for a brief period, there was a time during the week of release that I was ranked top ten in the world on NHL 19, even though I hadn't played competitively for over 5 years. Was fun knowing I could still beat people with skill, before everyone started figuring out exploits to score goals, because at that point it's just a game of gaming the system, instead of something resembling real hockey.
I've also tied or come within one second of a few individual act speedrun records for Sonic the Hedgehog 2, which is pretty cool. I don't have the patience to do full speedruns, but at least I know I can hang with some of the best.
