The game that's come closest to bringing back all those childhood memories of playing Zoo Tycoon 1. A great mix of simplicity and complexity, as its easy to get the hang of it yet it demands you be able to meet the requirements of the fish as well as giving you side missions to complete so its always giving you enough to do. The devs have been supporting this game with quality expansions for years and I've spent nearly 200 hours with it over the years and have gotten every achievement. Just a fantastic tycoon game.
