no computer role-playing game ever published might truly be a role-playing game
Wrong, look at this games: The Might and Magic Serie, Baldurs Gate and so on
They are not rpg. The role you are playing is limited by what the developpers put in the game. In a real RPG, I can choose to say anything to a NPC, or do anything to him.
In Baldur's Gate 1 I never got the option of proposing to Imoen, while playing a female dwarf. A true complete rpg would have allowed that.
http://en.wikipedia.org/wiki/Role-playing_gameThere, that definition is good enough, read ALL of it, and take a long look to pen-and-paper RPG, the first RPGs to be made, the original, basically the only real ones.
A role-playing game (RPG) is a broad family of games in which players assume the roles of characters in a fictional setting. Players take responsibility for acting out these roles within a narrative, either through literal acting, or through a process of structured decision-making or character development.[1] Actions taken within the game succeed or fail according to a formal system of rules and guidelines.
So that's a rpg. Where does Divinity2 not fit in this ?
What YOU define as a rpg is a rpg that uses exclusively D&D ruleset. And as much as that ruleset is nice (for monster bashing), it falls really short on many other points.
