from what Obsidian SAID about their new PoE IP game, it doesnt look Tripple A.
they said as much, its got a more restrictive space than lets say skyrim. a game thats 12 years old by now.
They are, at best, in the AA ballpark as you call it.
And if their previous work is anything to go by, its gonna be deep as a puddle.... wide as a puddle.
