No wonder there's little time for optimization. Sure, you can blame them for being over ambitious, but it's hardly the "technical competence" that is in question here
Edit: I wouldn't be surprised if Alpha Protocol had twice the content of ME due to all the possible ways to solve it (not just in terms of combat, but also dialogues and consequences), yet it's bound to be less polished, as I very much doubt it had a bigger budget than ME did.
