Hi Robert,
Wes from Playtiles here.
Thanks for the question and for caring about Season 1 games.
You're right, we don't offer Season 1 as a bundle anymore. There's a reason for it, and it's about respecting the developers who trusted us:
Our agreements with the amazing creators who made Season 1 games are limited to the season itself. After that, the rights revert fully to them. They own their work, and they're free to sell it wherever they want like here on itch.io, or anywhere else.
So while we can't sell you the bundle anymore, the games themselves aren't gone. They're just back with their creators.
Hope that helps.
