Bioware gets a bad rep for the gameplay in their games not being that fun but ME3 and Origins totally prove the opposite imo.

Origins is just tons of fun, the insane mage combos, the rogue positioning and backstabs, and building a tank that can take on even the end game drakes. Not to mention all the crowd control you can do with stuns and spells and how your entire party synergizes, and then there are also actually lots of really great fights in the game with the right amount of complexity. And actually much of this also applies to ME3, just two games with really good combat systems though i think most people will not experience those games in that way but it's absolutely there. I played Origins on nightmare and Me3 on insanity and I think they are tons of fun to play.
