[Suzerain of Sheol]

We had a thread on Mass Effect here, but it eventually turned into all Bioware games.

I liked the 2nd game better, which came as a surprise to me since I thought I would hate it for dumbing-down the RPG elements, but I found the actual gameplay to be amazingly improved. The fight where you rescue Garrus, and the one on board the Derelict Reaper are both among the most thrilling video game moments I've ever had.

The only thing that annoyed me about 2 slightly was being limited to only 2 party members. It got really hard to pick near the end, they gave you many awesome characters. I really liked Legion, too bad he joins so late in the game. I never got very far with unlocking his backstory, unfortunately.
