For me the games I'm most interested in are Ancestor's Legacy, Dead in Vinland, and X-Morph Defense. But on the other hand, and also not sure if I'll just pause the subscription and save the $12.
On one hand, Ancestor's Legacy looks amazing, I love that it's based on history, and it looks pretty epic...but on the other hand, it looks a lot like a Total War game, and how many of those do I have in my Steam library that I've barely played? I love tower defense games, and X-Morph just that, wrapped into an interesting story about leading an alien invasion, plus having your own unit that functions as a top-down shooter is intriguing...but as recently as last month it was just $4.50, and I typically only play the free tower defense games.
To me, Dead in Vinland is probably the most exciting game offered in the bundle, and if I don't pause the subscription this will be why. It combines RPG and survival, but it feels like they've really simplified the interfaces and instead focused their development on allowing a breadth in both areas, unlike many other games that try to do this. It looks like a fully functional survival game
and a fully functional RPG, either of which could stand on its own...but they're together.
