I like old games like WOLF because of the sandbox mode. It's so much fun. Plus using programs like Fhred you can change the names and give your simulation infinite prey. XD
I usually hack the names because it makes it more interesting to play it. :3
For those that can't get LION to work, the download from oldgames.sk/en works well because it's packaged with dosbox to do all the work for you. You just click and go. It's really dull, though. Time passes really slowly and it's almost impossible to have cubs
