No.
Bioware's best games are RPGs, and their amazing adaptation of D&D rules for computer games.
And I argue that ME2 is NOT an RPG.
It's a new take on the 90's Interactive Movie genre.
There's no inventory management, an experience/skill/leveling system which is so watered down as to not even be worth mentioning, watered down this and that.
It's an interactive movie.
And it is fantastic.
We should applaud it for rebirthing the genre in GLORIOUS fashion.
honestly i don't care what it is..RPG/Interactive Movie call it whatever u want but the fact remains that ME1 and ME2 will always be considered one of Bioware's finest creations.
