Warmark
Sentinel
just keep playing. I don't remember much about the game, but I remember being sort of lost too when I started, but then something happened and it all made sense.
I tried the demo and didn't have a clue what was going on, so took Fluent's word for it and bought the game.
That made all the difference as playing through the game itself is the tutorial.
Things are slowly explained bit by bit, now that I have a good working command of much of it I'm having a ton of fun, it's just so different than anything I've played before.
