After a long road, the waiting on We Happy Few for both Linux and Mac is about to come to an end. Not the happiest of endings either.
Originally funded on Kickstarter back in 2015 for $334,754 CA, Linux and Mac support was then announced for We Happy Few after the campaign had started. In 2017, it was announced that Compulsion Games teamed up with Gearbox Publishing to complete it.
Later in 2017 Compulsion Games announced work had begun on the ports, the whole game then had a delay and then Compulsion Games joined Microsoft in June of 2018 although they did confirmed then a Linux version was still happening.
Yesterday, they finally gave an update on what's been happening. The post on Kickstarter mentions that they "haven't reached a quality level that we are comfortable with" and they will not be selling or advertising a Linux or Mac version. However, they will offer a full refund to Linux/Mac backers and give out an unofficial Beta version as you will get to keep your copy even with the refund. They also said it will likely run slower than the Windows version, although on Linux it was said that Proton/Steam Play might be faster.
This Beta version for Linux was due with the 1.9 update released yesterday, although going by SteamDB it's not clear if that's actually happened yet and they've not said anything on it being released just yet.
After waiting so long, this is a real shame but they've handled this in a vastly better way than most other developers when they've been unable to do what they promised.
