Name a bad Valve game. I dare you.
They obviously intend HL3 to be a tour de force...and pushing back the date just whets the appetite while they work on other outstanding projects. There is not a single doubt in my mind that a new Half Life will be released.
Easy. Episode 1, Episode 2, TF2 and Left 4 Dead.
Also, that's exactly what I meant in my other post. Valve gets away with that ridiculous "oh they can take as long as they want". It's so laughable, because they are clearly showing they don't care about their fan base (in that interview they clearly say no one at Valve is "excited" to work on Half Life), yet that same fan base keeps praising them for essentially ignoring them...
It...makes...no...sense...
