I know. Interesting point. Super Mario got that treatment for 1993 on the SNES with the so called "All Stars" version and with later Game boy releases. I have played the original Doom. It was a masterpiece but famous and outstanding games that we know in years from now will be remade. I think it would be funny if they remade games like Grand theft Auto which I would expect in another 30 years. It's all about the money these days...
