Lost Eden should be worth checking out for any dinosaur fan. It's a point-and-click adventure with elements of strategy. It's been made by the same people who made Dune, and the mechanics are similar. Some backstory: the entire story is actually being told by Eloi, an old pterosaur (I think a Pteranodon), who recalls events from years ago. You play as Adam, a young prince from a famous human dinasty who has just reached maturity. Your father, the king, rules over a great fortress, the last remnant of a once advanced globe-spanning combined human-dinosaurian civilization. Outside the fortress walls the world is dominated by a tyrannosaurian army, which your father has given up on fighting long ago. The fortress population now mostly consists of humans and other primates, since there's been a fallout with the dinosarus and only few of them still live with humans. One of them is the aforementioned Eloi, who is now a middle-aged, but energetic and ever optimistic envoy, courier and diplomat. Eloi tells you there is a dinosaur waiting outside, a young Parasaurolophus, a compassionate, but goal-oriented seeress who reveals bits and pieces of a plan that could restore the might of the old civilization, and urges you to explore further. This will eventually lead you to the far ends of the world, and see many shocking things on your journey... The feel of the game is vaguely reminiscent of Dinotopia, but only vaguely. It is actually much darker and more mystical, as it involves communication with the dead, bizzare-looking characters, a creepy villain who taunts you repeatedly throughout the game, and explicit and implicit gore, topped all with a haunting soundtrack. You lead a retinue of characters with whom you can hold (scripted) conversations with by clicking on them. Some of them also have valuable abilities you will need make use of in various situations. The game does allow some flexibility in your interactions with the other characters, but if you go too far you can mess the game up. In that case you will have to star from the last save. By the way the recommendation is to save often, and since there can be only 3 saves at a time, move all save files from the game's save folder to a folder you've created for that purpose. The strategy part of the game is rather simple, and uses a map navigation system that gets some using to, but is actually practical once you get the gist of it. The game features fantastic 3D animation scenes for the year 1995. Even today they don't look all that bad. The greatest flaw of the game is its shortness. A dedicated player can finish it in 5 hours or less. The story is also cringeworthy in some parts (one character forcibly and hastily replaced with another). The strategy part can also get repetitive at times.
The game is to be played in DOSBox, and the game speed settings should be set 9000 cycles or more to have smooth animation.
Also, you will not be able to hear the whole soundtrack in the game, but it has some very interesting parts (it sounds quite unlike soundtracks in modern games), so a visit to YouTube is recommended.
