with the library disappearing games/ HELP!

its a common thing, steam kicks off some trash from time to time, the games remain in your library but they arent counted anymore towards your overall games count. sry bad english

I heard that some games are removed from the steam, but why just 57 games to delete?

u still have this "games" in your library and still can install and play them.
295 and 238 - just numbers

ouch, ook.

F2P games don't count

Steam keep removed games (from store) in your library but not counted as +1 in your profile.
You can check your own games here, even f2p

Log in and enter your steam ID here to highlight/filter the games in your library, that got removed

It's mostly shit like endorlight and other games, where the devs/publishers violated the rules so their games got removed from steam and don't give a +1 in your game counter any more. Of course there are also other games no longer in the store like dirt 3 or Alan Wake that still count as a game.
