• Added CoMaps (Add CoMaps #169)
• Added OSM Wiki's list of OSM based services (Add awesome-openstreetmap to OSM Wiki #168)
• Added PanoramaxGuessr and PanoGuessr games (Games: Add Geoguessr-likes #167)
• Added SCEE (Part of Lots of Additions #162)

Fixes #169
Fixes #168
Fixes #167

On SCEE, I was going to add it directly below StreetComplete, but because of this comment, I placed it at the bottom.

@Patkek You should modify the comments to use GitHub magic word Fixes, e.g. Fixes #169

That way, when PR is merged, issues will be closed automatically.

(And thanks for the PR!)

I did as you said. I hope I did it correctly.
