You're exposed to four climate change events: 400 AD, 420 AD, 435 AD, and 442 AD. You seem to have already run into lack of money for construction, which will come back to bite you because. 3,000 denari a turn is very low compared to the potential income by losing territory. Late game civil research addresses this through corruption reduction and tax rate increases. By holding onto so much land early on, you're hamstringing your economic potential. I'm close to finishing my legendary WRE campaign, so I'll add in what I can:

Has anybody else played the Western Roman Empire with the intention of keeping it entirely together? How has it gone? Meanwhile, plague seems to be sweeping across and there's never any money for construction (what's left goes to repairing sacked settlements or raising troops). If an army gets defeated, it's a catastrophe- I've had to save and re-load on a couple of occasions to get the desired outcome. And, with public order gradually wearing down, rebellions are going to break out well away from the frontiers where the armies are.

Every city battle must be fought out (much of the West's military potential is wasted if city-battles are autoresolved). Africa is far too wide for 2 half-stacks (one of which was originally a stack in Spain) to defend it. Diplomacy is delicate, and if too many tribes go to war at once, then keeping the Rhine-Danube frontier may not be possible. Thanks to technology and a few economic building constructions, I'm making nearly 3,000 gpt and have a food surplus of nearly 500.Д«ut it's not easy. The only rebellions to occur have been in provinces being invaded- where I usually have an army on hand to deal with it quickly. Only one settlement- Wales- was lost, due to being razed. Ostrogoths have lost a stack and the other stack left (and when they return, there's two stacks waiting for them in Pannonia). The Visigoths, Suebi, and Vandals have been wiped out. Granted, I played on Normal (I'm not sure this goal would actually be possible on Legendary or Very Hard, and if it is, it'd require a player with far more skill than me).ДЎ1 turns in (Fall 397AD), things are fairly together. I started a game today with one goal- play the Western Roman Empire without losing territory.
