head to head
LEGO Battles asks more than Dungeon Keeper 2, and the gap is reads.

Optimization · Pure Optimization
Villainous dungeon management game about luring monsters and crushing do-gooder heroes.

Optimization · Pure Optimization
A simplified RTS testing basic build-order economy with light multiplayer prediction.
Dungeon Keeper 2 leans Optimization (Pure Optimization); LEGO Battles leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Keeper 2
Slap-and-drop micro and possession combat need quick hands.
LEGO Battles
Stylus micro on DS is gentle, not twitch-defining
LEGO Battles leans clearly harder on reads.
Dungeon Keeper 2
Hero waves and rival keepers run on scripts.
LEGO Battles
Multiplayer skirmishes add light human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Keeper 2
Hero party timing and creature moods vary mildly.
LEGO Battles
Map fog and treasure hunts hide modest information
Dungeon Keeper 2 leans a little harder on optimization, though the gap is small.
Dungeon Keeper 2
Dungeon layout, creature economy and research are solvable.
LEGO Battles
Build orders and base economy decide simplified RTS matches
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
