Seas of Blood… this is going to be a tough discussion for me, because I have to admit this was the gamebook which I read/played more often than any other when I was a kid. Whether this was due to thematic preference, due to gameplay-related strengths or other aspects, we will probably find out. However, I cannot guarantee that I can stay objective at all times. Please excuse the occasional drift into nostalgia.
Anno 1602 is a classic city building sim. You're founding a settlement in a world of islands, and develop it by providing space to live and necessary goods to the citizens. In mission mode, you have to fulfill single tasks, but in free play, it's your final goal to beat your opponents from the surrounding cities to achieve sovereign rule over the islands. At the beginning, you choose a appropriate island to found your first settlement. Right from the start, you have to deliver basic goods to your people.
Captain Verdeterre's Plunder is a humorous, very short game. The player takes over the role of the first mate on a sinking pirate ship. It is his task to save the most valuable treasures which are spread all over the ship.
And all that happens under the watchful eye and the sharp tongue of the titular captain who (surprisingly at first) is actually a rat. As it looks like, quite a greedy one at that, for (almost) nothing seems to be more important to him than getting the right sum out of it.
