I started unemployed and got offered the job of managing the Wales U-19 squad within a couple of days, so I accepted. The thing is, I really didn't plan to go in for national management, so I figured having a database with just the complete British Isles would be enough. I know it should be obvious, but if I'm going to stick with this, do I have to add more countries so that I can play against them? If the answer is "yes", do I have to add them as playable? Are there countries that would be good choices as additions?
I know the fact that I have to ask this shows that I'm not ready for the challenge, but I feel kind of obliged to give it a go, at least.
Apologies if this has been asked thousands of times, but I couldn't refine the search enough to see whether there was a thread on this subject.
