Are you sure you got your info right? I'd not be surprised if they've been stuck at $60 after adjusting for inflation, i.e. costing around $30 in 1995.
100%. Easily verified by doing Google image searches for "SNES game ad". Most games were in the $50-70 range (Note that you'll see some images with prices up to $95, but that's Canadian dollars). It was only as the SNES generation was ending that you started seeing some games around $30-40.
