I believe it. Unfortunately I have a strange compulsion to gain as much money as possible (not so I can spend it on soldiers, though, which is why it is strange. I routinely have hundreds of thousands of denarii within 20-30 turns in Rome: Total Realism, because I do virtually nothing but build up economic infrastructure and hoard my gold. Thankfully, it means I can, and do, bribe any rebel army that happens to stir up trouble.), which eventually means the ridiculous port upgrades are going to get built. Once I get the hang of spending money, rather than amassing vast wealth and only spending it for the purposes of amassing more wealth, I'm sure I'll be fine and have the willpower to resist the urge to build those outrageous upgrades.

Cheers.
