Game Dev Tycoon has a wide appeal to different audiences. As well as being a great introduction to management sims, there's enough to keep long time fans interested as well. It's fun, sometimes silly in the best kind of way, and hard to put down once you get started.
Parkasaurus is the type of game where you're never wondering what you should be doing, but never overwhelmed by the number of tasks. Coupled with the colourful graphics and the fact it doesn't take itself too seriously, this is a wonderful version of a park management game.
