Which games had really well thought out and engaging leveling system?

Skyrim was a good baseline I believe, not perfect but engaging and not too punishing. Path of Exile seems convoluted to me, to many skills the dont make any real impact. Fable was effective but very simple. Oblivion tried hard for a deep leveling system but was basically broken. Witcher 3 was pretty run of the mill (I thought, despite the praise the game gets).

I'm trying to find something where there are several viable different playstyles. And it's always good when combat isn't the only way to proceed.

Alex Bruce gave a pair of talks at GDC 2014 on the development process of Antichamber (trailer)

In the first talk he talked about the journey from Unreal mod to full game, presenting at game festivals, networking, the grueling work of getting the game to market, and the lessons he learned along the way:

Antichamber: An Overnight Success, Seven Years In The Making

In the second talk he went over the iterative design process, and how he tweaked things based on how people interacted with the game (spoilers):

Antichamber: Three Years of Hardcore Iteration

SSS is finally over and those sweet (although not as sweet as they used to be) deals are gone. What games have you gotten your hands on?

I didn't get too many games this time around. I actually found a bunch of games in my library that I didn't know I had, so I felt like I had enough to play for a while.

Games I bought:

• Stick Fight
• For the King
• Cuphead

There isn't really a great mechanic for learning skills and languages in dungeons and dragons. This makes it a bit lacking if there is a certain amount of off-time between adventures and missions. It would be cool to think some sort of mundane dnd. Like mini-games in video game RPGs that make your character a little bit more personal. A quirks mechanic, that adds a certain way your character acts in the every day or what your character normally does. The risk is that it could turn into too much of a dice roller and the players might engage less with the story. What do you think?
