I have this crazy idea to put landbridges between Britain and Gaul, Iberia and North Africa, and (sic) Sicily and Carthage.

I've read some info on making landbridges here and at Twcenter, but I still have some questions.

I've seen a landbridge done between Iberia and North Africa, but would the others be possible? I'm guessing the Britain-to-Gaul one would, but what about the Sicily-Carthage one?

I'm sick and tired of Casse never going for the continent, even with BI.exe, of Lusotann never going for Africa or Carthage never bothering to reconquer Sicily.
