Had a player who rolled a 4 on one of his stats. Barbarian, so he dumped it in intelligence. He decided to roleplay a 4 intelligence barbarian.
He ended up killed by guards because he was just too stupid to understand their orders.
Also had a fighter who managed to make a very good impression on a local crimelord and managed to talk him into agreeing to some demands he really would not have, because the player managed to spin an incredible story. Had I adhered to his low charisma score of 6, I would have had to tell him that his character would never be able to sell that story.
Right now my current campaign has a wizard who is starting up a trans-planar merchant empire, even though his charisma score doesn't scream "smooth merchant."
Awesome creative roleplaying takes precedence over stats, in my opinion. Adherence to stats means people are stuck in a role they can't escape from. A character with low charisma is always going to have social problems, even though people can learn to open up. Intelligence can be increased through study, even though stats don't reflect this and even wisdom can be learned, whereas that stats barely change.
Scanning planets in ME2 wasn't even okay in the first playthrough. The randomized nature and inability to do anything while you were scanning made things tedious.
Advantage inquisition has is that on your second and third playthrough, the hunt is over as you know where to find the stuff you need, and you can gather while you quest.
And yet, restrictions are the only way to get the variety you crave. Without restrictions in Origins, every mage would be the same. Every rogue would be the same. Every warrior would be the same. Restrictions are what breed variety.
