For me I mostly enjoy POTC.
Though sometimes I do find it a little redundant and a little glitchy. But I'm of course expecting that.
I realize this game is new therefore problems and what not are to be expected. And I also expect this is a learn and go situation for them as well.
Lag can be an issue on the "ideal" oceans when there are more people and it can get a little more glitchy, but like you said it's easier to opperate on a "quiet" ocean when you're a lone wolf, as am I.
I wish they had developed more story line than just one before releasing it though. That seems kind of silly. I have already finished my black pearl quest and it just kinda blows my mind that they would release something that's not even complete. I can understand upgrading and adding things, but not even having a full story line in place?
Overall it's good
devs just need to keep learning and tweaking and we need to keep helping them with ideas and helping to identify bugs and glitches.
