This same topic has come up more than once on Pinside and it's true. The games are not maintained at all. As far as I know they have 2 locations at MSP with pins, in terminals C and F (named 'Aurora Borealis' arcade I believe). Currently the other location at MSP has Mustang and Rolling Stones and Rolling Stones is an absolute mess (I was last through there a week ago Friday.) The op's could really care less unfortunately.
