I'm from the Netherlands and I entered the world of Xsyon yesterday. Met a few people and everyone's been very kind so far.
After running into Fatboy, I decided to join his tribe.
The only "sandbox" MMO I played so far has been SWG( after NGE only) and I'll miss the mix of themepark and sandbox there, but I think I'll enjoy myself in Xsyon. The idea behind it sounds really great and I look forward to being a part of a developing world like this.
