It used to be that Chrono Trigger was my go-to answer for this, because that is to me the gold standard of RPG games. Its not about being the first, longest or most sold, but rather the most complete. And CT is easily the very best exprience from every metric i can think of.
I say "used to be" cause I dont really think this question has a 100% satisfying answer, i dont think modern audiences care. Theres other games that might feel more relevant from a "historical" perspective, but current gamers would just react Meh to them.
