I judge a country very much so on its people usually. Other traits I would care about is the climate, food and landscapes.
But, usually when someone asks if I like a certain country, it is the people I have met from those countries that dictate my answer. I find that, much like a stereotype people from certain countries tend to act certain ways towards other people from other countries. In general, some are nice, others tend to be filled with rude and mean people. Now I am not saying if you are from a country I find has rude or immature people, I am not saying everyone from there is like that. I have seen enough to have an opinion of a countries people as a whole however.
So to answer your question, Germany is one of my favorite countries and I find it has some of the nicest people. That is what I think of first, is the great and friendly people I have met there. It is also one of my favorite languages. Really cool music scene and festivals, and since it is that time of year Oktoberfest! One of my friends is going this year.
