All because they want to sell the game to players like my granddaughter: Playing DA2: "Grams, how do you make it so only one thing makes you better? I can't remember what gives who what and what takes away stuff like health or power from them." [I patiently explain stats for the fifth time that hour] *click, click click.* with mouse moving randomly and kid's eyes closed. "I can't remember it all, it's too complicated so I did it the fun way." This is a teen and unfortunately the type of players they tried to make the game acceptable for.
If you have to think, the game isn't fun, or so the younger generation tells me. It's got a big giant easy button that you can't unpress, you are stuck in easy mode, even if you are capable of thinking, that is not a system requirement so, the game can't expect anyone to do that. The operator is, after all a part of the system the game is being played on.
