It's hard even for me to believe this but the answer is The Elder Scrolls III: Morrowind. My favorite RPG of all time
Same here, on both accounts. ;)
Morrowind broke with a lot of conventions that RPGs had at that time, and it took a while until I actually realized this. With my first character, I just dabbled around a bit, and found that my character was rather weak - not surprising in hindsight since I kept doing things that his class wasn't good at.
I then started another character and played in the way that many RPGs of that time _had_ to be played - meaning, I tried to game the system in every way possible. I ran and jumped around for hours because I noticed that this was a seemingly risk-free way to increase my level, and I assumed that increasing my level was a good thing (what it really did, though, was causing the game to spawn enemies that I wasn't in any way prepared for because because I never trained a single useful combat skill). I systematically stole every single movable item in every settlement, spending hours hauling the stuff to the merchants and selling it for pennies, because I assumed that I would have to stockpile money for some outrageously expensive late-game purchases. In short, I played the game in a thoroughly unenjoyable way because I expected it to have the same flaws as other RPGs at that time.
I shelved the game for several months, and at some time I picked it up again and just let it flow. Instead of trying to game the system, I actually role-played my character - a playing style that most computer RPGs did not allow, or did allow only to a very limited extent. And that was when Morrowind started to unfold its beauty. The immense freedom of choice, the rich background, the lack of any forced progression - it all clicked into place once I started to treat Morrowind as an actual
role-playing game, and not just as a set of numbers that I would need to min-max in order to achieve some pre-determined end goal.
Since then, Morrowind has become the game that I probably spent the most time with. :)
