Although I've only played the demo of it, the game Sol Survivor seems very fun to me. Of course, I'm the type of guy who usually would get insulted for "camping" on a map playing defensively rather than run around like crazy making myself a target. This game is all about building base defenses while the enemy is advancing to kill everyone in your base. There's a little bit of weirdness, since the name of the enemy is the "acendency" and they seek to kill your colonists and literally steal their souls, but apart from the encyclopedia I didn't see any weirdness of that type in the gameplay, just an onslaught of wave after wave of enemies to kill with base defenses and orbital weaponry.
