While I do consider Valve to be a very consistent developer in the vein of Bioware and Bethesda, the one thing the company doesn't do for me is have every franchise be something that I love to the core. While I'm a huge Team Fortress 2 fan and will defend any naysayers of Portal, stuff like the Half-Life series I just plain cannot get into. Sections go on longer than they should, the shooting is adequate but not exceptional (aside from the Gravity Gun of course) and I find it personally hard to care about a story where the most all-important figure in the entire thing (you) doesn't say one word. Which makes the Left 4 Dead games curious entries in that it's kind of in both camps: a game I really love but only in short bursts and even then, I still find things too gripe about. The core gameplay's still intact and I even prefer this game to the sequel but this game is quite fun but at a certain point, it feels like you've played it far longer than the content actually feels.
