Halloween "I Want A Gunpla" Sale (itch.io)

Another day, another sale.

This time you get 13 horror titles for $9.86.

There doesn't seem to be any good cause tied to that one, unless you consider the creator getting a Gundam figure to be one (weird, I know...).

...and to avoid spamming this section with even more sales, here is the Videogame Hacks TTRPG Bundle. 39 titles for $10.

Another one. Tabletop Science-Fiction. 69 (nice) titles for $25.
