that is so unfortunate
even if it differs a little, i think it fits quite well as a supplement.
unfortunately you can't buy adult games via steam in germany. that's why it's an advantage that there are other options besides steam.
the developers of these games should also be aware of this, because because steam germany blocks this content, fewer games of this type can be sold.
personally, i am happy to be plugged via “itch”.
in case that sounds a bit strange, i had everything translated with deepl.
