Damn! Sooooo many great new IP's this gen, limiting it to a top 5 seems a bit unfair. I can think of at least 10 new IPs I'd like to give a shout out to. So honourable mentions (in no particular order): Heavy Rain, Dragon Age, Resistance, inFamous, Assassin's Creed, Batman Arkham Assylum, Gears of War, Darksiders, Alan Wake, Sports Champions, Wii series, Dance Central ... and the list goes on...great generation this.
