The short answer is that it's Sonic 3 & Knuckles, because (1) my sister (who was my best friend growing up) used to play it with me all the time, I cherish those memories, and (2) classic Sonic is love and classic Sonic is life. Oh, and (3) playing it now is cathartic/therapeutic for a long-winded personal reason.
The long answer is loooooooooooong, and I fully intend to write it all out if you're interested. But I wanted to get this answer out now, lest ADHD do a thing and distract me, lol. Thanks for the question! :) <3
