heres one of the most annoying things in the current games industry.
Because sequals like fallout or oblivion were "dumbed down" from the previous iteration, people now, ironically, are afraid of innovation.

Let me tell you something, Fallout was dumbed down for the EXACT same reason you are giving here. fear, fear that the fanbase might reject it.
An isometric game? In this time? no way, it HAS to be a shooter.
Same with Divine Divinity. A Turn based RPG? In the west? no it has to be like diablo (not that divine divinity is bad)

Its not about the game beeing dumbed down. Right now you go a "non RTWP Baldurs gate game? Heresy!"
Its the exact same reason thsoe "dumbed down" games exist. Conservativism and fear of innovatin.
