Haha, no. Rome maintains a strong MP community, and while I don't play MP myself (CD key died in a cleaning incident

), I know better than to think my strategies against the AI are superior to the ones MP players use. On MP, you're playing against other humans, with real minds, that vary from really stupid to extremely intelligent. On campaign, you fight an AI that is extremely stupid, and you can win just about every battle with the most basic of tactics.
tl;dr respect the MP players. Most can probably beat you in minutes in a battle.
