I will only list really free or Play4Free (micropayment ***) games or mods delivered on Steam
I will not add games announced like free but with limitation ingame, as capped main content
I will not add games listed as beta on Steam
...and I will actively update this thread XD

* As default, no masked install links are Windows only supported
** As default, no masked items are gaming content, addon or resources
*** Free to Play games (and any other free game available on Steam) will only be listed if these games does not apply basic restrictions for players that does not realize micropayment, as aggressive level cap/cut, restricted main areas or access to essential features, like main questline progression, basic trading or chat system
