frelled :
Makes me wonder how many resources Valve spent in this conversion that should be used for FINISHING HALF LIFE 3! Jesus Valve, throw me a bone here.
Steam alone is worth something like $2 billion a year, I think they have plenty of money to throw around and I doubt this cost them that much as they ported HL2 to OpenGL a while ago. I doubt it took much to move over.
And they are working on HL3. Plenty of people have taken tours where there is always one room that is off limits to tours.
Also we need to consider that Source 2 was confirmed which means they probably went the route of a new game engine as Source is pretty old, even though it still looks good to me.
