I once played a campaign of Rome Total War as the Julii and I decided that once I'd secured the Italian peninsular and blocked the mountain passes with armies that I would not expand for 100 turns.
It had it's pros and cons. I was able to devote a lot of time and money to my economy, which became huge, but when i did venture out, it was against huge, established factions.
I did a very similar thing a few years ago: Very hard/very hard difficulty, no turns limit but decided to just defend on a whim. Never turned on Rome so I only held Northern Italy.
Everything from Northern Spain to the Steppes was controlled by my enemies; Briton and Dacia. They were allies.
My economy never had the chance to pick up, every army I created was very nearly destroyed a few turns later during the constant invasions.
Then, finally, I managed a heroic victory that left me with half a professional post-Marius army. Quickly discovered that the entire garrison force of the enemy superpowers was pathetic and steam-rolled them with that small army - when I say steam-rolled I mean that army got to the Baltic coast with almost no reinforcements, taking half a dozen cities on route.
That campaign taught me a lot about how to use Roman Legions.
Also doing an underground minecraft playthrough trying to build a huge library. Several hundred bookcases in I'm about 1/3 done.
