What is YOUR game of the gen ? - Please explain your reasons :-)

I'll go with Mass Effect 2. All three Mass Effects were great experiences, but Mass Effect 2 was my favorite from beginning to END. The game play was a massive improvement over the first (No crazy Mako). The story and the universe built in the story is the best I've seen in gaming in general. The cast of characters are deep, had good back stories, and personalities. The loyalty missions were amazing.
