Tracks, developed by Whoop Group, is a simulation game and it has arguably the most simple premise of any game: build a train set consisting of pieces such as curves, turntables, corkscrews and so much more. After that, you are left to your own on how you want to set it up. Tracks introduces you to a rather detailed tutorial where it goes through the controls and the various mechanics. This tutorial pops up every time you start up the game and begin a project, but of course you can skip the tutorial if you choose to do so. The game modes currently in are Free Play, and Passengers, where you build a set of tracks to pick up passengers and drop them off at designated areas. As of now, the Modern Apartment is the only scenario to play Passengers in, but more areas are to be expected as updates roll around.
