In the promo vid on their site, there are a couple of people gaming. Is this alluding to the fact that you can game on RHEL or that it powers the backend of games?
Just curious...
2) Steam now bundles Wine and lots of games are tested and semi-officially supported with it now, bumps the playable fraction to more like 60-70%—and you can enable it for all games with a settings checkbox, too, and more often than not it works.
You can game on RHEL but it wouldn't be my first choice of distro for it - IMO, Ubuntu and Fedora are both better-suited for that task.
Also RHEL development moves sloooowly. This is a feature and one of the main reasons to go with RHEL instead of not only unsupported distros but also supported-but-faster-moving distros, kind of like on Windows LTSB (I know to little about both to compare them, but enough to know that in certain organzations the promise that it will stay the way it is and by default only receive security updates is a huge feature.)
And I believe Ubuntu has finally started doing it as well in the most recent release?
It's rolling release, including the whole stack that's supporting games. And they have a wrapper package that will install steam and its dependencies.
