POTCO has Double Trouble

[Davy]

RTS is actually pretty fun... they have 3 versions of it. It's very similar to POTCO, except you can't walk around. It's all browser based. You can attack fellow pirates for money, though. It is also easier to level up. POTCO = better game than POTBS and RTS, but all three are very fun.

I doubt the others are as good. =\
Just because, since you have to pay for full access to POTCO, Disney is getting more money that they can put into the game.
If the other sites are 100% free, I'm not saying they're awful...but they probubly aren't as high in quality.
