I have been wanting to since I first got the core set way back in 2012 to build a full Imperial TIE wing of 72 fighters. (48 TIE Fighters, 12 Interceptors and 12 TIE Bombers or do a post ESB wing with 36 TF and 24 Interceptors and 12 Bombers) Along with 8 Lambda shuttles to round out a full ISD compliment with the current ships we have. Would still need Assault Gunboats, Sentinel Landing Craft, AT-AT Barges, Stormtrooper/Zero-G Trooper transports and Skipray Blastboats for a complete ISD loadout. Heres hopeing FFG gets around to making all those ships!
I also have the crazy idea of wanting to build the full 181st wing of 36 Interceptors. Then also a squadron (12) each of Phantoms, Defenders and the Advanced.
Then on the Rebel side just get a squadron each of the fighters, X/Y/A/B/E. A full Rebel fighter wing is 36 fighters, except on either Home One or the Independence. I don't remember which it was that had somewhere around 10 squadrons in their Wing.
Of course I haven't even gotten close to any of my goals. I only have one of each ship except for three TIE Fighters and three X-Wings from buying the core set and the single packs and the x-wing from the rebel transport.
So anyone else done anything crazy like that or planning to ?
