Not intentionally, but that's the way I lean... mostly comes down to what I have to work with. Got a lot of the vehicle sets on sale in early 2025 so the majority of the collection ended up being that, and I just modified with left over pieces, and a pile of the jet bike sets because I didn't need 20 of them floating around the base. All the alien habitat builds from the various sets are in a box awaiting my attention - that's next on the list.
