Reasonable; I play through HL 2 at least twice a year, it is actually THAT GOOD! 
There is one thing I miss in most games, the multiplayer I like the most; cooperative play! There should be heaps more of that, can't be that hard to implement if you're building an extensive SP campaign and a full and varied MP part? (I realize it'd have to be in the core design of the game though but coop is a huge selling point, especially in FPS and RPG games).
