Played
Bayonetta - This was okay, but for me was ruined by the QTE's so I stopped playing it out of frustration.
Final Fantasy VII - Love it.
Final Fantasy VIII - Love it.
Final Fantasy IX - Really good.
Mass Effect - Love it.
Starcraft - Was alright, but I prefer Warcraft to Starcraft.
Starcraft II Wings of Liberty - Ditto the above (thanks Pike).
Elder Scrolls V: Skyrim - Really good.

I both envy your workload and send commiserations. Basically I'm in that place where I wish I had more time to play all the games that I want to play, but at the same time I don't have that time and having such a workload would only serve to lessen my enjoyment of each game as I would feel rather rushed.
