Looking forward to refurbishing a Sky Soldiers game I recently purchased!

Hi All,

I'm new here and looking forward to reading/posting and learning about arcade game system refurbishing.  I recently found a nice Sky Soldiers arcade machine on craigslist, drove an hour to Derry, NH to buy it, threw it in the back of my pickup and brought back home up in Maine.  The cabinet is a little rough and the joystick seems a bit sloppy but overall it plays well.  When I opened the back of the cabinet there was a poster on the inside for a Centipede game (Guess it got swapped out).  The system does have an upgraded power supply but looks mostly original.  My plan was to toss in a Jamma 60 in 1 but now I'm feeling that I would rather keep it original and just clean it up and restore the cabinet.  Not sure.  Is the game worth saving?
