Okay fine, but arguing that the side quests involve doing more of what the character is good at is not really the point. I even mention that in spider-man all you do is more spider-man things, "oh no spider-man stop this crime. Oh no spider-man find out who did this crime, etc etc." It's not really the gameplay of the side quests that make important or engaging side quests, it's the context in which those side quests take place.*Looks at the side quest list*
Yo, a LOT of those side quest that aren’t contracts involve hunting something
In a perfect world, you are enjoying the core gameplay as it pertains to the main story, therefore well written side quests that provide you more reasons to do the gameplay that you are already having fun with is the ultimate ideal.
I mean what player ever says, "You know I love running around and doing things in Skyrim, but you know what I which these side quests had less sword fighting, sneaking, magicing, and istead had more Go-Kart racing!"?
While there is some merit to sometimes have completely unique activities within the side quests, the actual goal of the game should be to provide the players contextual motivation to get the extra gameplay out of the game. This concept is going to be even more important going forward considering the price hike for next gen gaming, which will make shitty side quests feel even worse because sunk cost and all that.
