Played through Expeditions : Conquistador again about a month ago.Great game.Only downside for me was the sometimes clunky camera on the overworld area.
Anyway I'll be picking up viking over the weekend, steam reviews currently 96% positive with 27 reviews.Anyone else tried it yet? Appears to have more depth than conquistador did.
