Woah, you weren't kidding about the environments - they're gorgeous! I do love a game that has proper attention paid to the surroundings.
One thing that does slightly irritate me about Guild Wars (and quite a few other games like it) is that it suffers badly from ICS - Impractical Clothing Syndrome. WOMEN OF GW! Y U NO WEAR PROPER CLOTHES/ARMOUR?! HOW U STILL HAVE ALL LIMBS?
