Don't worry, you'll get something preinstalled for sure. You won't even know about it

Seriously thought, albeit a bit OT. I really like the fact that Jolla comes with a very minimalistic set of preinstalled apps. I have my objections to their choice of "bare minimum" (for example, I would leave out Gallery and add a file manager instead) but it is a step in the right direction. Chess or any other game is a job for the app store.
