Ok, so the last time i played a total war game was 7 years ago and while at it, i had some medicore success on the campaign map, eventually getting stuck at trying to defend my sertlements from sieges that came from every side of the map, but at least i could destroy a few factions. Now, 7 years later i suddenly got the itch to try out the new installment. I picked the suebi faction and had to restart the game 4 times, because after a few turns the pc overwhelms me. I am playing on normal. At the vey start i occupy 2 settlements, because after a few turns i find it impossible to crack on the defenses of these cities as they hold much greater forces then i can muster in such a short ammount of time. But even then, the enemy starts raiding me with 20/20 armies, at the same time my cities are not having enough food, army attritions etc. even though i build food buildings.
I watched the ingame tutorials and tried to figure out some tactics on my own, not browsing through the RT2 forums. Everybody is saying how this game is very easy, so it seems i am doing something absolutely wrong. Can someone give me some tips?
