I've bought arcade boards that cost like $250 and I have no idea how much I've spent playing Pop'n Music (arcade) over the years. Then again I guess there are multiple versions of Pop'n so that probably doesn't count.
Street fighter 2 turbo hyper fighting on the SNES, about 20 years ago it cost £79.99 from a now long gone store in Meadowhall shopping mall England.
And people today say games are expensive.
