lol one eye... (I uninstalled that silly Halo Pelican thingy too!)
For me, if it's totally unrealistic, or items that I don't use like most of the jets, all of the bush trips, landing challenges, training exercises or discovery flights.. well they're removed too, which not only saves almost 30gb to use for other items/add-on I want or consider usable items but that saves needlessly loading them each time the sim starts which considerably speeds up the loading of the sim!
