I asked about why the link sent it to Steam on the main thread here instead of the CoG site:
Champion of the Gods: Will you serve the gods or overthrow them? - #3 by dfabulich,
And this was the answer:
dfabulich
That’s intentional this time. We’re asking people to buy the Steam version rather than buying on our website. Increasing our Steam sales will help us ship more games on Steam.
If you’re unable/unwilling to buy the game on Steam, you can also buy on the Chrome Web Store, or email us at support@choiceofgames.com and we’ll figure something out!<
