Yakuza 0 exists you know. It’s all in there.

Eh, really depends on the use case. For example if you want to edit something distributed in a psd format gimp won’t even tell you something got imported wrong. So the file will import but will look wrong.

A lot of it is single time purchases, therapy is a subscription service.
