The Walking Dead is one of my favorite games this year. I'd be glad to vote for it to be game of the year, it deserves to be atleast nominated.
Played trough episode 5 today, and it was pretty amazing. But especially emotional. I won't spoil stuff, unless we get a spoiler thread for this, but its definatly worth playing till the end.
I personally love Heavy Rain, and I'd love to see another one of these games. It was made by the same developers that made Fahrenheit, and also easily worth playing. Sadly its a PS3 exclusive >.<
