Knights of the Cross is a deck-building game loosely based on a historical novel written in the 1900s called Krzyżacy. I say loosely based because the game does follow the events portrayed in the books regarding Medieval Poland. However, It also features magic and busty elven women in string bikinis.
The Last Spell is a rogue-lite where you have to protect a small settlement from hoards of monsters. While there are certainly some tower defense elements, the vast majority of the monster-slaying is going to come from a handful of randomly generated, but customizable heroes. The catch is, the game is entirely turned-based.
It’s distressingly easy to disregard any game with simplistic visuals. Steam has poisoned the well, so to speak. Take a gander at the new release page at any given time and your eyes will be assaulted by low-effort asset flips and a disturbing amount of hentai. The thing is, there are some gems buried in that rubbish, but few people are willing to shove their hands into that sewage to fish them out.
In Deathloop, you play as a Colt Vahn. A man trapped inside a time-loop on some Bioshock flavored Island called Black Reef. After every night or death, Colt wakes up on the beach of the previous morning. The only way to break to loop is to find a way to kill 8 visionaries in one day without dying.
