I have Europa 1912 but to be honest I find it a bit of a pain, because you have to decide what ticket set to use each time you want to play and then sort all the tickets. We never use the warehouses.
what we do with the sets is keep the three main ones separate: Original, Big Cities and Extended. So it is pretty easy to just grab one pack and play with it. It only becomes a pain after playing mega. Which we rarely do. It is mostly original or Big Cities. The one thing that annoys me is that the new long routes have a different colour back to the other tickets. Makes them easy to spot. Oh and the fact that one of the new "normal" routes is longer than any of the "long" routes.
