Pirates of the Carribbean by Bethesda ?
No, sadly
no that isn't it.
The game is really looks nice and is your typical run-of-the mill high phantasy game. The buildings look like they could be placed in the cities in medieval Europe or maybe 18th Century middle Europe (or Germany of today).
You don't move much around on the ship. You just embark from the ship. The ship then sails away again. There's a big market where you talk to merchants and the like and buy stuff & things. I never quite got what I was supposed to do, though.
A comment also on the Prince of Qiun game:
I really liked the story in the game, didn't notive the (bad) voice acting. What I did notice was the horrible control sceme that when I clicked on my character(s), it took them forever to get where I wanted them to go. And as I said earlier, the game seems to be a full blown rpg game, which it is, but only in towns and such. In the wasteland it is more of an action rpg where everything just jumps at you when they have the chance.
Now, I don't mind combat that is hard, but I do think that sometimes developers need to decide whether they want to make a full blown rpg or an action rpg. Diablo's combat is hard too, but you know that eventually you will make it - especially since you can add skill levels to your skill tree when you level up. It didn't pretend to be a full blown rpg, though, when quests were given, as most quest given in Diablo just was an excuse to get out there and fight some monsters. In Prince of Quinn, it seems that you had the full blown rpg in the towns whereas you had more diabloplay style in the open areas between cities, even with the monsters respawning, I think. Anyway, I've found that the combat wasn't any fun, no matter if I retreated and fought the monsters one by one or took them all on at the same time.
I'm glad, however, that someone did like this game...
