+1. That is exactly how I feel as a GG customer.
I have Steam too, due to other games I like being only available with it. But I don't like their policy, their monopoly; I want to have freedom as a paying customer to use the game as I like, instead of being baby-sitted by Steam and having to be extra careful not to allow automatic updates, never buy an expansion somewhere else, doing extra fuss to copy out of Steam repository or no mod works, and similar amenities. I don't want MP, don't chat, don't need spam about other Steam games, may easily do without achievements (what are they good for, anyway?).
I am waiting to see how this issue with the promised Steam keys will be solved. The moment I will receive them for CK2 + all the DLCs I have (everything but the "customizer" and SOA) I will make my opinion if it is worth to continue as a buyer of Paradox games.
I can pretty much give a -1 to this I guess since it's the exact opposite for me, I want to go from GG to Steam.
