Crusader Computings Prehistoric Adventure is a well crafted adventure that includes an element of horrors - education!! You get to learn about dinosaurs while solving the problems. They're big.
Actually, even armed with clue sheet all I've seen so far a a dinosaur bone, but I'm sure I'll come across them soon.
Basically, you have to get to the island of dinosaurs to find the main ingredient for the potion of eternal life which has kept the old man in the centre of Stonehenge young for centuries...
You kick off in a high class burger bar with a dress code and American Express sign in the window. You'll need the burger later, along with something to quench the thirst, otherwise it'll be a case of water, water everywhere...
Finding the map is a bit of a pain. First map the endless plains, then find the coppice. Use the rod to find the underground stream. And with a bit of manual labour, you'll have your map.
There are a number of problems an the first section of the game - the bit that happens before you reach the island, that is - and they're all pretty tough. I think they might be just a bit too tough, but I suppose you'll at least be kept busy.
Included with the game you get a dinosaur poster so you can spot who's who when you finally get to the lost world. Even so, I can't help feeling that £9.95 is a bit steep for a text-only adventure.
