When it comes to Zynga vs. Valve, I have a feeling that enough anti-Zynga sentiment will be built up for them to be defeated. Hopefully.
Zynga has been getting a
lot of votes, I think Valve has a very tough battle ahead.
Some developer who makes games for Facebook. Apparently they are advertising the competition in their games or something, and getting a bunch of votes.
It's within the rules for a developer to advertise the contest, in fact I'm sure the Escapist loves having the contest advertised.
Turbine won last year by really trumpeting the contest - they mainly develop MMOs so it was easy to get the word out to a lot of people. I don't see Zynga's tactics being all that different but as a casual game developer (who provides free games) they reach an exceptionally large number of people.
I'd rather not see Zynga win but I don't think they're operating all that differently than some of the other developers.
