The Banner Saga: Factions
The turn-based multiplayer combat component was released as a free standalone game, called The Banner Saga: Factions, prior to the release of the full game. It became available to backers on 18 February 2013 and will be available to the public on 25 February. Factions allow players to pit teams of six combatants, chosen from 16 classes, against each other.
I didn't participate in the kickstarter for the full game but I figured I'd give this a shot when I saw it on steam. So far the art is excellent as expected, but the tactical gameplay is what's really grabbed me. It's completely sold me on getting the story portion on release. I've only played 10 or so games so I don't know how long it will hold my attention but every game I learn something new that I can apply in my next game. So far the match making seems decent. There's been some lag but nothing game breaking. There's an in game store where you can buy skins or upgraded characters but I haven't felt held back by not using it.
So if that sounds like your kind of thing try it out! And if anyone wants to play a friend game hit me up. I'm also more than happy to answer any questions.
