I find with Civ V or 0ad the bots always arrived with a massive army (even on easy) when I have barely got a shed and a dude scratching out furrows with an asses jawbone. Still find them fun, most recently I got annihilated by tanks and 5 air squadrons, playing Civ V. For some reason my charioteers and pikes didn't hold up well.
