came across this:
"Beginning in 1999, following the success of its first game, Valve began to threaten Sierra that it would halt or slow development of the remaining games it was obligated to develop unless Sierra relinquished certain rights under the 1997 agreements. Sierra eventually capitulated to these demands and, relying on misrepresentations by Valve, entered into a new software publishing agreement (SPA) with Valve in 2001.
That doesn't come as much of a surprise but it does make it really hard to respect Valve. I'd say it's pretty safe to say development of this game has been heavily dependent on how ready steam was to distrubute it.
As I see it,way back in 97 Valve said Sierra could market, distribute, and publish HL and several other titles. (I'm assuming to include sequels). After the success of their first game Valve was emboldened to make Sierra give them a better deal or never see a sequel come out for their flagship game. Sierra said "ok, but we still get ot distribute it right?" Valve says "yes". Valve then turns around and creates steam, aimed at distrubuting the game completely outside of the Sierra company.
Valve should be in breach of contract if they sell HL2 to the general public via steam. If they provide it to all the ATI video card buyers I don't think they will have a problem. But providing it via steam is the same as letting someone else publish it and distribute it at the same time. Profits will be cut significantly. I don't see a problem with them doing this with other games outside the half life franchise but in this case I think Vivendia has a right to their share of profits. If selling the game on steam sends the same dollars back to sierra/vivendi I'm sure this wouldn't be a problem.
As for that internet cafe complaint, Valve should be compensated the same as any other sale of their software.
