Knowing me I'll max out all my stats before beating it but I could conceivably go on to beat the game right now. Back in the day you had to write down the clues and figure out how to solve the puzzles to get to the end, without dungeon maps and FAQs to gather the clues in one place. I guess it's kind of cheating but it's what I've done with FF6 and 7 and the like since I was a kid and Exodus is harder than those games.
I mean, what's the hardest puzzle in FF6? The clock in Zozo? What next? Locke changing clothes in South Figaro? Pssht.
