Chrono Trigger is probably my favorite RPG of all time.
I bought it on the day it came out, having to sell half my SNES collection to afford it, and I sucked the marrow out of that game. I played through to all 14 endings, I got probably every secret, I did every side quest. My characters were all level 100 (Star Star). I could beat Lavos in one round, by the time I finally bored of it.
I still pick it up now and again, and grind through the opening Festival, doing everything I can to get Chrono acquitted at the later trial. I was convinced by the urban legends as a kid that it was possible to avoid the whole prison portion of the game. Of course, no, it isn’t possible, but urban legends in video games are still fascinating in their grip even decades later.
