Controllers have more buttons than previous generations and that offers the player more options to play the game. It's not 'Required' but it might seem like a waste of a button if it isn't utilized.
Thankfully there is an indie scene that sticks to basic controls while trying to keep the genre of games they create fresh/relevant with the current times.
It's sometimes tough because on a day I require mental stimulation in a game, those crazy button inputs are almost exactly what I need, whereas on days where I just want to zone out I often turn on a low input button/simple game and just relax while playing it. Different speeds for different moods I suppose but I am glad both are available to me.
Yes, modern games can easily get complicated with the over input but that doesn't mean 'simple' games have been left by the wayside in favor of more input, it just means that now these 'simple' games have a niche to fill that certain gamers are content with.
