EDIT: Removed negative recommendation due to Sony giving in to not enforce PSN.

@Steam @Gaben @GabeNewell you should REALLY enforce game makers to have things like 3rd party clients, 2nd/3rd party account-making as well as other tools needed to being INCLUDED AND WORKING before they release their game. Same goes for EULA and requirements, while HW-Requirements may be soft due to updates.
Everything else will things make go haywire (as G-Man said:") from time to time (").
This will also lead to a lot of money wasted and loosing trust in Steam as well, due to you being connected as seller and thus information-upfront-granter. Please think about a system, where you have two layers: the games and possible "extended versions" as well as DLC - and where you link possible 2nd/3rd-party stuff to the main games and their ext versions.
Also make use of a popup in case of 2nd/3rd-party tools or other stuff.

Delivering products not "as is" might be problematic in EU-countries. Imagine you get a car and it stops working after 3 months with the automotive saying "ey man, we fixed that your car runs without XYZ". The same day a company will decease to be.

Proud of you since you refunded a lot of the copies sold. In germany you'd say "Ehren-Steam". Btw: I love Gabes "uaaah" scream in the commercial he was on as well as him being very natural. Sponsor him a bottle of "Hacker Pschorr" german beer from my Steam Wallet (https://www.hacker-pschorr.de/). And have him do more secret pop-ups from time to time :D
