If you want a far better remake than this, play Hostile Waters. It's a dozen years old, but still holds up well. It has good AI (on both sides), awesome missions, and is a pretty difficult game that'll easily last you a dozen hours if not quite a bit more. (A playthrough typically takes me around 20 hours, but I easily take 2 to 3 hours on some of the later islands.)
I've been bugging GOG about putting it in their collection for awhile now.
