Well, that would be a long list on my end. I guess I would like to see about 80% of the world. But I will try to make a shorter list by picking just the top favorites.
New Zealand
Canada
Norway
Thailand
Iceland (maybe together with Greenland, which is not far away from there)
Ireland
Argentina
Chile
South Africa
Australia
Switzerland and USA (have been to both of them, but would really love to go again)
The main reason for basically all the countries listed is the great landscape. Seeing a different culture and beautiful cities is a plus of course.
One thing I would really like to know: Why is Poland on your list?
It somewhat stands out on your list, because the other countries are known for being tourist attractions in some way.....but Poland not so much.
