FSX/P3D. I must say, developer RF SceneryBuilding is increasingly making itself apparent on my radar the the quality of work is getting more and more impressive. This doesn't come without it's consequences however. The team recently came under fire from two other development teams for having stolen source materials in past works. As I understand, all issues have been ratified and this dev continues to move full speed ahead. I'm also rather pleased to see more decent coverage of Italy as well prompting me to wonder where they will strike next. Calabria is now available.
