Army building is a costly addiction
I started mine off with the BM vehicons but sold the bulk off (left with a few now that I'm trying to clear).
Got a good number of Sweeps from the Generation deluxe line.
Unfortunately I also collect GI Joes and army built a bit there as well.
Like some have already mentioned... It does take up a lot of space.
But hey, whatever makes you happy
The Metroplexes you keep tho... That's a little hard to justify unless you're intending to customize them to various titan colors.
They take up too much space!
