These three games will be on a significant discount from their regular price, and because of the way Crowd Sales work, even more discounted if lots of people buy them!
Along with that initial discount, for every 10 people that buy a copy, the price of that game goes down even more.
You don’t have to buy ExoBase to get either of the other games.
If you know someone who might like them, I’d love it if you could share the sale page; it has how-to-play videos for all three games.
