FSX/P3D. And I am very happy with what I am seeing in the latest screenshots of Monterrey. When ADX was the very first entity in the community to introductory and report on MagMexico and it's been a joy to see this team improve with each release. But what's also good is seeing the team start to live up to the prices they have been charging. MagMexico is deffo a team you will want to be keeping your eyes on. The last time I told you to keep your eyes on a little known Mexican development team, it was years ago. The name? Taxi2Gate! So mark my words, keep your eyes on MagMexico. These guys are going to do great things! Check out all the development shots on this project via the source link.
