What you said was sarcastic, but you make a serious point.

I absolutely refuse to expose myself on the internet to virus and other malicious digital attacks, that I do not have to be exposed to. Dropping windows entirely was one of the single best steps I took in minimizing that attack surface.

I do not have resources to dedicate to having yet another untrusted machine with expensive software for the sake of one "free" piece of software that amounts to little more than a game (even though I really like games).

Luckily it (appears to) runs on linux.

Since it is not open source how do I know it doesn't contain a virus? It would not be the first time such has happened.

I got seriously downvoted on that one, but it was worth it.
