Good to know before you choose

Pure ITS features are enabled only when the game is launched from the ITS App. Launching directly or through a third-party launcher starts the game without Pure ITS integration.

Products or routes that require another developer's own launcher may not operate alongside Pure ITS content. Please consider this if another launcher is essential to your setup.

App-based launching is a permanent part of the Pure ITS platform because it enables these enhanced systems. ITS may occasionally provide complimentary add-on editions at its discretion. Free versions of add-ons and included scenarios are not guaranteed. Purchase decisions should be based on the content listed with the product.
