Stranded II is what the name suggests: You're a castaway on a desert island and must build yourself the wherewithal of survival from scratch, Robinson Crusoe-style.
It's implemented in rather crude 3D (using Blitz Basic). Primarily, it's a crafting sim: you need to figure out how to build yourself an axe and other tools, how to start a fire, how to construct shelter, and so on. The main mechanism for doing so is borrowed from adventure games: use object with object to combine.
It's quite well done, within its limited palate; one criticism is that the learning curve is perhaps the inverse of what it should be. That is, you may well die in the first day or two, of starvation or by getting eaten yourself, because you haven't figured out what you need to do yet. Subsequent days become easier, although the game does throw interesting twists at you from time to time.
