Quote 1 = arrogance. Quotes 2 and 4 = wisdom.
Quote 3 would have to read "Gamers don’t just want beautiful graphics, sounds and epic stories" and have some sort of follow up to that statement, to make it an acceptable point of view - but it's impossible to know where to put the emphasis in that sentence or if there was a further point to be made.
Also, if it's in quotes, you don't need to italicise.
