I don't get the "samey" feel in TTRPGs or board games or card games (that I can recall), regardless of which one I run.
But I'm going to talk about an instance of "sameyness" in games that does register with me and does have a verifiable impact on play.
If someone wants to use this to help depict how "sameyness" emerges for them, that might be helpful.
Basketball.
I'm defending a player who possesses the following offensive profile:
- Right handed.
- Has pretty solid handles (can dribble and maintain control) going both left and right.
- Terrible finisher at the rim (particularly left-handed).
- Loves 1 hard dribble left > step back jumpshot.
- Cannot dribble right and pull up and hit jumpshot reliably.
- Loves to go right and try to draw a double team and kick the ball to the open man (he may try to finish, but he's a bad finisher).
So those are 7 attributes that amount to a sort of "sameyness" in play, because:
1) I have no fear of him being able to take the ball to the rim and threaten to score. Because of this I can crowd him. Also, I'm confident in my ability to change direction and protect against his dribble drive.
2) I know he isn't going to dribble right and pull-up for a jumpshot, so if he goes right, I can easily give ground.
3) I know if he dribbles left, he is almost_always going to go with 1 hard escape dribble > step back jumpshot. Therefore, I crowd him hard on any dribble left and I stay on his right shoulder to challenge the stepback jumpshot.
Donezo. Overwhelmingly, I can look this kind of player down pretty trivially. I'm not getting beat right on the dribble drive and I'm going to be challenging that step back jumpshot. What ends up happening during actual play looks "samey" everytime he touches the ball (because he's limited himself and I'm limiting him more) and what is happening in my mind while I defend him feels "samey" because I'm not inhabiting a complex mental space (the kind that I would be handling with a versatile, multi-threat offensive player).
Jiujitsu also has a very nice analog (and would be more apt to D&D), but I think this was is much more accessible and hopefully has explanatory power.
