You might have seen recently that I covered the upcoming updates for Roblox, and now it's here blocking Wine with their new anti-cheat. This means you won't be able to play it on Linux any more, at all, unless you find some sort of special workaround.
Previously the roll-out of this update was being tested only with some users. Now though it's here for everyone giving a 64 bit client and introducing their Hyperion anti-cheat software which they are intentionally blocking Wine with. Naturally plenty of Roblox fans on Linux are upset by this, asking their team for updates on what their plans are.
In a fresh statement on their official developer forum one of their staff said this, in reply to users asking about updates in regards to Linux support:
Hi - thanks for the question. I definitely get where you’re coming from, and as you point out, you deserve a clear, good-faith answer. Unfortunately that answer is essentially “no.”
From a personal perspective, a lot of people at Roblox would love to support Linux (including me). Practically speaking, there’s just no way for us to justify it. If we release a client, we have to support it, which means QA, CS, documentation, etc., all of which is much more difficult on a fragmented platform. We release weekly on a half-dozen platforms. Adding in the time to test, debug, and release a Linux client would be expensive, which means time taken away from improving Roblox on our current platforms.
Even Wine support is difficult because of anti-cheat. As wonderful as it would be to allow Roblox under Wine, the number of users who would take advantage of that is minuscule compared with our other platforms, and it’s not worthwhile if it makes it easy for exploiters to cheat.
I’m sorry to be such a downer about this, but it’s the reality. We have to spend our time porting to and supporting the platforms that will grow our community.
Again, I’m personally sorry to have to say this. Way back in 2000 I had a few patches accepted into the kernel, and I led the port of Roblox game servers from Windows to Linux several years ago. From a technical and philosophical perspective, it would be a wonderful thing to do. But our first responsibility is to our overall community, and the opportunity cost of supporting a Linux client is far, far too high to justify.
They're clearly not going to be releasing a Native Linux build, which I think most people probably already knew, but at least previously they repeatedly said that Wine was a "priority" to support but now it doesn't sound as likely going by the above.
