Poor sequel of a great francise
The bad things: a lot.
Worst game stability I ever seen in the last 10 years. the game crashes with or without any reason, anytime. So, you must save a lot and reload a lot more for continious play.
Poor game universe. Very few interactions with NPC. Main story linear and short. A lot of buildings (banks, churches etc.) are not useable. I think the producers made the launch of this game without finished it. I remeber one of the precedesesor of this game (Sea Dogs) with a more complicate and passionate storyline and a lot of interactions.
Stupid AI. Even you manage to gather the most powerfull naval force of the Caribbean, the AI will continue to send against you stupid and weak enemies. This encounters will annoy every player. In case that AI it is your ally (ships in your squadron), it will excelate by inactivity.
Bottom conclusion: It is a game launch without any substantial tests and, above all, without any respect for the consumers. Shame on the publisher!
