Oh. I thought you HAD a guide for us. lol
Actually just finished the campaign tonight/this morning. Tried a couple of times previously over the holidays but didn't like my progress and restarted. There is a nice little cutscene at the end btw but no specific Steam achievement (though I earn my first military one to add to my culture victory). Unfortunately haven't played Rome 2 much as compared to other TW titles, but I did enjoy this DLC.
Tips you say? Well here is one that I could of used - read the objectives, duh! Seriously, my first two campaigns I focused on the northeastern Gaulic territories when I should have setup a defensive line there and stayed friendly while expanding in the northwestern territories, which I did on my last campaign.
Not sure how easy this will be for the vets, but just playing on Normal and had a terrific Gaulish onslaught coming my way; luckily I just achieved the victory conditions before they could crush my northern holdings. I should mention I like to turtle and build-up a bit before expanding too much. In hindsight I could have formed more mixed armies instead of legions and later cohorts (supported by giant arty) but managed financially as I only needed 4-5 armies to hold my frontline and push north. Had a few friendly Gauls for a long time until everyone turned on me.
All in all the most fun I have had with Rome 2 to date. Had some "hiccups" with sieges, but generally decent AI behaviour. Campaign wise I thought the AI did well, and like I said towards the end you really feel the Gaulish horde coming for you. :) Better and quicker players will probably beat this on higher levels with ease. For those who like to take their time you may find this DLC worth picking up.
Best regards
