First off I live in the US.

My question is that I tried to install the game before using the US method. I ended up stopping after about 3 hours because it was getting confusing and I was surprised how much room it was taking. I am extremely bored right now so I decided to try it again and wanted to try the European version, since it is a lot more strait forward. I just want to know if they end up leading to separate servers or anything of the sort.

Thank you in advance!

The version does not matter, as you are using a separate program to connect. For further information view the sticky tutorials.
