Enebias: P.S. I remember Bones from Risen 2. That guy is completely nuts! :P
By the way, do you know if there are other known faces around? Also, I wonder why Pirhanha Bytes changed the protagonist with the last installment.
Another question: did PB implemented the shadows right, this time? My PC could run Risen 2 and more demanding games maximized with no problem, yet high shadow details there "paralyzed" my framerate in a few areas.
Unfortunately I cant really answer any of your questions, I have only played Risen 1, although I have R2, I had forgotten I had it and bought R3 on impulse because I was going to get Ravens Cry, but was advised against it, hence I am playing out of sequence.
As regards shadows etc. I have a pretty crap PC and the game plays fine on it mostly even though my machine is below spec for the game, I haven't noticed anything bad in particular about the shadows, but that could just be my PC.
I am about 17 hours in and have just left the first island to continue the main quest and still having a blast. When you leave the first main island, you gat attacked at sea and the controls were fine but I couldn't invert the aim, but I expect there will be more sea combat, which is a nice addition.
If I had a complaint, its that there are probably too many quests (most are optional), but I have not yet had a crap quest, they have all been interesting so far.
