DE:HR is definitely my favorite game in a long time. After playing it through twice in a row, I took a 4 month break and played Skyrim and Mass Effect 2. Skyrim was great for a while, then it became too easy and repetitive. ME2 was a lot of fun, but I feel no compulsion to play it again. On a whim I started up a new game of DE yesterday and I was engrossed again from the beginning. I can't wait for another DE4.
