Uh Halflife 2 is no where near being an underdog and is probably on the other end of the spectrum being overy-hyped. Have you got so far into the mentality that popular games must suck to the point of pretending popular games that you like are actually underdogs? Either that or you hang around largely biased communities of people like at the gamefaqs forum. Considering the number of people that still play Halflife and its mods I'm quite sure there is quite the large crowd eargrly waiting for its release.
Congratulations, you've completely misinterperated my post!
I was rooting for the "underdog" referring to the creator of this thread, he was voting for Halo 2, and how it'll "blow it outta' the water", well I was refferring in-statement to that, more or less sarcasm aside.
In any case, playing Doom 2 multiplayer is the greatest thing ever. Especially when the servers have mouse look on!
