I'm not good at strategy games but I'm pretty skeptical about the balance. Although nothing like that would matter to me because I booted it up again due to nostalgia. The unit models and especially the voice lines will be remembered till I bite the dust.
The writing and acting in this game is both batshit and phenomenal, it's a 2003 Teen-rated game where your first missions are a nuclear terrorist attack in China, the siege of Baghdad, and a terrorist attack on a dam followed by hails and cheers as the tide sweeps away civilians and enemies alike. Oh, and this game was written by Rachel Bilson's dad.
