Simpler is not equal to dumber.

You can imagine a complex set of rule where there is a clear and dumb OP strategy that trumps all. That is a complex set of rule that has no depth.

You can imagine a simple set of rule that has depth (like Chess), and complexify it with irrelevant set of rules that have ultimately no change on the gameplay. That is a complex (bloated) set of rules that adds no benefit to the simpler set of rules.

There are gags about this, for instance medieval men in a village explaining the rules of a game of cards during hours and hours with plenty of made up words.
