Check out Lanes & Games in Cambridge. Just checked and it's ~20 miles from Natick center. They have good newer games (just got GB in recently) and Mike who runs it keeps them in great condition. I think the game list on the site is a little outdated as he's swapped some out, but definitely worth your time:

If you can swing a longer drive (probably an hour), head up to Pinball Wizard in Pelham, NH. Best amount of new and old games around here. 150 Bridge St, Pelham, NH 03076
Hope this helps and have fun!
