I bought the BG I and II at Gog.com and I want to install BGTrilogy with TDD.
So I have some questions:

1) What is the correct order of installation?
I tried this:

1º BG I
2º BG II
3º bg2fixpack
4º TDD
5º Worldmap
6º BGTrilogy WeiDU

2) What I choose to install: Big Picture compatibility mod or worldmap for Tutu?

3) What is the difference between the huge and large worldmap? Only the size? What is better?

4) What is the difference between the new worldmap and the clothmap style map for Throne of Bhaal? What is better?

Thanks.
