I've never heard about it until this year, bought it on a sale, and got blown away. It's got so much in one game! Although I suspect it's aimed for younger players, with its low violence, vibrant graphics, cartoonish characters and occasional "family entertainment" style orchestral phrases, it's interesting enough for adult to enjoy as well. It's got non-linear gameplay with side missions, races, mini-games, stealth elements and cooperative gameplay with AI characters, economy with two "currencies", upgradable vehicle... A bit of climbing, a lot of fighting. And you got to make photos of various creatures instead (or plus to) killing them! Real fun. I needed a few tweaks I found in the forums to get it run well on my machine. I haven't finished it yet, so I'm sure there'll be more to tell. Highly recommended!
One of the best, or maybe the best game of its genre. Enjoyed it more than any of LucasArts adventure games (tough competition), and played it through a few times. Great animation and graphics (for the standards of that period - the resolutions were much lower back then). Highly recommended to anyone who likes adventure games.
