Let's take your example and think about how an hypotetical Duke Nukem 3D remake should be if it wanted to sell a big amount of copies: shiny graphics (so far, so good), regenerating health, damped down difficulty, pointless cinematics and narrative (with the Duke? Really?), reduced number of enemies and extremely slowed down gameplay to allow gamepad support and console versions, because if it is not multiplatfrom it is not profitable.
Call me elitist or whatever you want, but there is a big difference between a console shooter and a PC one: the speed and frenetic action of the old 3D realms build engine games cannot
be reproduced on consoles, and the PC version will have to suffer a shallow gameplay because making two different versions would cost too much.
This is true and I would not want a dumbed down Duke 3d such as the one on N64 with all the dirty content removed albeit having better graphics. I am dreaming of a Duke 3d with something like Wolfenstein: The New Order graphics, with all gameplay kept the same including holding all weapons, keeping the profanity and humour, same 1:1 levels and speed of the game and even the old music and sound should be copied over, it should be made for PC 1st then ported.
