Great collection! There's quite a lot of heavy hitting classics in there. I'm jelly of your Metal Slug 4 and Alpha Mission 2. AES collecting is a slippery, expensive slope indeed. I was collecting AES for awhile before I ended up realizing I was spending the same amount on carts that I could for an actual cabinet. So now I have 2 cabs that take my wallet into the back alley at night and do unspeakable things when nobody is watching....but at least I can play some sweet shooters.
