I was browsing the Ubisoft sale right now, I had all these Asscreed, Farcry and Watchdogs 2 staring at me, at ridiculously low prices and I literally thought "eh, not worth it".
Play Gothic trilogy or first Risen. That's open- world game done right.
It's currently on sale on GOG (-76%). Just don't buy it with Arcania or Forsaken Gods.
