FSDreamTeam scenery is 30% off in the marketplace. I own KORD and it is fantastic. If you fly Vatsim - or get generally frustrated with the MSFS default KORD taxiways not lining up with charts, this fixes all those problems. In my opinion, it’s one of the best 3rd party airports in the US as far as quality goes. I’m debating whether to get Louisville and Key West.
Worth mentioning that the sale applies on their store as well (using the code FSDTXBOX30) and on Simmarket for those who don’t care using the official marketplace.
