I don't buy the cumbersomeness argument for Linux games. A lot of games in the past and today has been distributed as Linux binaries. Most famously Quake and Unreal Tournament series had native Linux binaries on disks and they worked well until I migrated to 64 bit distributions. I'm sure they'll work equally fine if I multi-arch my installations.

Many of the games bundled by HumbleBundle as downloadable setups have Linux binaries. Some are re-built as 64 bit binaries and updated long after the bundle has closed.

I still play Darwinia on my 64 bit Linux system occasionally.

Most of these games are distributed as .tar.gz archives, too.

I can accept and respect not creating Linux builds as engineering (using Windows only APIs, libraries, etc.) and business (not enough market) decisions, but cumbersomeness is not an excuse, it's a result of the other related choices.

In my book, if a company doesn't want to support Linux, they can tell it bluntly, but telling "we want to, but it's hard, and this is Linux's problem" doesn't sound sincere even remotely.
