Dead Cells is a game I always have installed just to pick it up in bursts of 30 minutes or an hour.
It’s a roguelike, it’s challenging and it’s easy to pick up any time.
Even though it has levels, the intended way to play it is in runs. You start the game, start a new run, and try to go as far as you can, you die and repeat.
Multiple paths to choose, so it never becomes boring, and the levels are generated, so you can’t memorize everything.
It seems they consider themselves complimentary with OpenStreetMap, as stated on their FAQ https://overturemaps.org/resources/faq/#
Overture is a data-centric map project, not a community of individual map editors. Therefore, Overture is intended to be complementary to OSM. We combine OSM with other sources to produce new open map data sets. Overture data will be available for use by the OpenStreetMap community under compatible open data licenses. Overture members are encouraged to contribute to OSM directly.
I don’t know a lot about any of both projects, but it seems fair.
Heroic is a client for GOG and Epic Launcher, so if I install a game from there, I use Heroic.
Lutris is more generic, and has specific script installers per game, so I use Lutris as a fallback if the game is from somewhere else, or the game does not correctly work with Heroic.
Then, as a third fallback, I try to install the game with Wine directly, then add it a shortcut on Steam to benefit from Proton through Steam. In the above cases (Heroic and Lutris), they would be using their own packaged version of Wine/Proton, so it’s worth to try it before giving up.
