Ha, that's a silly thing to say and you're silly for saying it. Every game can be broken down to even less actions if you really wanted to.
Shooters:
1. Aim gun
2. Shoot gun
3. Find next enemy
RTS:
1. Build Units
2. Attack Enemy Base
Turn Based Strategy:
1. Research Good Tech
2. Build large army
3. Defeat enemy factions
JRPG:
1. Ignore plot
2. Grind levels
3. Enjoy pretty cinematic
Besides, I haven't found Skyrim repetitive at all if you actually do the quests. The Daedric quests, the Thieves Guild quests, the Dark Brotherhood Quests, the Civil War quests, and the Main Plot quests all have great set pieces and interesting and varied goals.
