All games are repetition.
Football. Get the ball, score a goal.
Racing games. Drive car around the track.
FPS. Get a gun, kill someone, then kill someone else.
Monopoly. Go round the board, get properties.
RDR2. Go to this place, do mission (probably involves riding a horse and shooting guns). Go to that place, do mission (probably involves riding a horse and shooting guns), next mission.
PacMan. Eat blobs, avoid ghosts, move rpund maze.
Notice how in none of those examples I spend 90 minutes doing literally nothing at all, and where me even being present in any way influences how the game goes. In football games like PES and FIFA I can skip the pre-game warmup, I dont have to watch a bunch of dudes stretching their legs for 90 minutes (which absurdly enough would still be more exciting than watching a white dot on a black background get bigger). In racing games I dont have to watch for 90 minutes how the team is polishing my car, which, again, would be visually more stimulating than what SC in ED is.
This is the only forums I know where 'is doing absolutely nothing for long stretches of time good game design and fun?' a legit question with people debating both sides. It boggles the mind when you take a step back.
