Game prices are funny. They've been the same since the 90s. I remember spending $59.99 on new SNES games. Price increases are way overdue inflation-wise.
Well, at the same time, it was never that expensive to produce games on discs, and now there's practically no cost to sell digital versions, which is a huge market. There have been some big games here and there that have been sold for more than $60. It could be that $60 is the sweet spot.
