Yar might be interested to hear that 2K Games and Firaxis have confirmed the upcoming February release of Sid Meier's Pirates! on PSP.
Mixing strategy and adventure elements, Pirates! - previously released on PC and Xbox - gives you control of a small boat and sends you out into the Caribbean in search of swash to buckle and treasure to loot.
There's sea battles, even the odd land tussle and plenty of amusing mini-games - sword-fighting, but also dancing - to tackle on your way to becoming a notorious pirate with a sizable fleet.
Additions to the PSP version include ad-hoc multiplayer for up to four players, as well as a few new treasure hunts. Enough to make it attractive to people who didn't try it on the other systems, then.
Plus it's due out quite soon - 23rd February, says 2K Games - and you can see how it's shaping up in these screenshots.
