My top 3 best would be Widelands, Battle for Wesnoth and FreeOrion. But the ones that I play most of the time ae the simple quick games from KDE Games collection :)
Agree with this. Also they extensively use OpenQA CI and testing framework and it is what makes the rolling release openSUSE Tumbleweed the most stable rolling release distribution I have used since they can quickly catch an updated package that would cause problems and halt it being introduced. And even if something problematic would get through they really have excellent integration of BTRFS snapshoting with zypper and GRUB and system in general so you can easily boot from the last known working snapshot before the problematic update. And I would also say they have the best integration of KDE Plasma and KDE software of any distro out there. so yeah for these reasons I also consider openSUSE the bets GNU/Linux distribution out there.
