A note on pricing. I can see the arguments and will not present my view but will present how others have handled pricing:

a) Kickstart games with committed price structure (those who have done kickstart believe that they cannot undersell the prices kickstart people played until the game has been released):
examples: planetary something or other charged a certain amount for game only/alpha/beta and therefore charged the same amount when they made EA available:

b) kickstart game with significantly delay adjusted policy but held pricing (and policy change) across the line with adjustment:
for example grim-dawn charged for alpha/beta but due to significant delays after allowing people with alpha and later beta to play several months released the game to all backers and for steam they released the game as EA with current selling price (which is higher than when on kickstart but lower than prices they were selling for alpha/beta).

c) straight EA games - some offer prices at a release price but many offer at discount (blackguards, M&M X, starbound (no clue if this is release price or regular price) kerbal space (slowing raising prices as they approach release), gemni 2, ...)

I guess I will make a comment; perhaps D:OS should throw in an old game like DD or BD as a bonus for those who buy early (this is what M&M X did with M&M 6).

Anyway it is much easier for non kickstart games to do EA than kickstart games because they are not beholden to a given price structure but quite frankly the whiners are just that whiners. They simply do not have to buy the game. Most of the time whining is about trying to get something (it is a form of negotiation after all - if I complain maybe they will toss me a bone) conversely there is something to be said about 'paying' testers so tossing a small bone isn't always a bad idea.

Having said all of this none of it is relevant to myself (I have a kickstart copy) and quite frankly I'm getting really tired of the whine crowd. Posting a suggestion in a constructive fashion can be quite useful but frequently that is not the case on the steam board. No clue why the blackguard EA has gone so smoothly - probably because the devs jumped in there right away with honest answers and they have done frequently updates.
