Gave Fractured Space a try since it has a free weekend going. It's a MOBA with a sci-fi capital ship battle flavor. Two teams of 5 ships slug it out to capture territory and buffs, in hopes of eventually capturing the enemy base. It's an interesting concept and I like the aesthetic, but it's still very alpha. Situational awareness can be a challenge in 3D in a first person or over the shoulder camera view, and the game servers have a bad tendency to lag. But it is one to watch for if you like MOBAs. I especially like that it's not like LOL or DOTA in that frenetic clicking and pinpoint mouse control will not automatically guarantee that all the fights go to preteens on caffeine. The combat is slower paced and emphasizes strategy and teamwork rather than finger dexterity and quick reflexes. So, good for old farts like me.
Also gave Sunless Sea a shot. It's an interesting top-down 2d exploration survival game that reminds me a lot of an old PC game called Solar Winds. The game takes place in the "Unterzee," a vast undergound ocean with islands and cities and monsters and pirates. You are the captain of a ship, and you must explore, negotiate, trade and fight your way toward your goals, ranging from mere survival to cushy retirement to founding a new nation. It is heavily story driven with RPG elements, you can buy a better ships or better equipment for your ship, you upgrade your stats which determine your success chance in doing diplomatic, sneaky, or courageous things. Every game's world is randomly regenerated, and the game is very harsh - you will die a lot, and dying means you start over with a new captain, inheriting a little of what the previous captain had. It's a very engaging game. I'm not sure if I'll actually buy it or not when the free weekend is over, but it's definitely one to check out if you're into roguelikes, maritime adventure, and lovecraftian horror.
