Imagine for a moment that YOUR FAVORITE GAME was released this year. Now imagine it's the year 2026, and it's been 16 years since you've seen a YOUR FAVORITE GAME on a console. Sure, there was the PSP or DS release (and probably one or two more PSP/PSP2/DS/TS/DS2 games since then), and maybe some really bad first-person YOUR FAVORITE GAME based off the original series. Imagine the years going by, where the full-fledged sequel to YOUR FAVORITE GAME was. But now it's 2026, and the remaining guys that made YOUR FAVORITE GAME are getting together to make a sequel, and it looks like the series you used to love instead of some lousy spinoffs. Imagine how much you'd be anticipating that from just the trailer alone.
If anything, the 2007 sequels (and prequel- GoWIII, Mass Effect 2, Bioshock 2, SMG 2, and Halo Reach are all followups to 2007 games) should be lower on the list. Starcraft II should be higher.
