Title: Battle for Arrakis or Building of a Dynasty

When i got this game on my PC, back in the 90ties, it was called Dune II: Building of a Dynasty.

But later, i found out that it was called Dune II: Battle for Arrakis.

What is the correct title? If any.

Because, and this is a fact, there are versions, were it is called Battle for Arrakis and some were it is called Building of a Dynasty.

My theory is that Building of a Dynasty was the European version (because i am from Europe, and that is the version i got), and that Battle for Arrakis is the American one.

If someone has the correct story, then please inlighten me!
