I picked up EU:Rome a while back and love it.
EU is the most incredibly series of games ever.
I would highly recommend EU3 plus the two expansion packs, Napoleon's Ambition and In Nomine.
Eu needs both XP's to be a good game, but with it the game is very good.
U:R is a SWEET ASS culmination of the EU experience. I highly recommend it for anyone with a more then passing interest into strategy game play.
Europa Universalis 3, however, is simply excellent with all expansions installed
it was an incredibly deep game.
loved EU3 + expansion.
The expansions together take a great game and make it into a phenominal game.
By the way, these games are now available on Impulse. EU III and both expasions.
