I just watched the E3 presentation of Half Life 2... and I _REALLY_ hope that this game will be able to run under Linux, even though Value made it clear they were not going to port HL1 to Linux (which probably rules out a native port of the sequel).

But if you haven't seen this 22mins presentation, I would advice you to get a hold of it - it's 500 megs mind you. - You can either pay gamespy for the download or use Bittorrent (like I did).

It's mindblowing, the physics engine is incredible, as is the whole enviroment... and the story looks like it could be nearly as good as the first one ( I for one really dug the storyline in Half Life and all it's addons - I played everyone of them, except blue shift).
