I had to vote no towards moving entirely to Steam.
I've heard enough stories, as well as once knew someone who lost their entire $200+ steam Library over a false cheating accusation, their account was terminated, and when they contacted Steam's support in an attempt to fix the situation, they got "Not our problem" in response.
I also have my concerns on the funding.. For instance, how is purchasing going to be effected by steam? Will you guys be losing a percentage of the revenue? Or will the prices have to be hiked up to insure that steam gets their cash out of the situation.
I'd rather we had the option to stay independent from steam, but looking at the polls, it seems the majority of people are in favor of steam exclusivity without taking into mind what could happen to the others.
I'll play the game regardless, as always. I just certainly hope that if you go to it, Steam works out the way everyone likes to think it will. Things don't always go perfectly..
