It seems that today, Source SDK Base 2007 and Half-Life 2 Episodes 1 & 2 are being converted to Steampipe. Even Portal and Half-Life 2 (not the episodic version) are being converted to it.
Do you guys think this has to do with the phasing out of the Source SDK launcher?
Probably.
Notice that they have their own tools in their \bin folder, now.
every mod all at once proceeds to break and never be repaired
Out of curiosity, does downloading the new update break Black Mesa?
No.
I can confirm that Crypt19’s correct. The game was still working after all the source games and sdk base 2007 were converted. I wonder if it’s because the sdk base folder is still in my account folder.
I would say yes.
So does this redownload the entire games in the new format or something
Basically. It even takes longer than installation and everything! 
oh dear
Already made the conversion to all the supported game
