Wintersday 2009!
Well, I don’t know how it is for you, but I can still remember my first Wintersday. And I sucked at snowball fights.
I’m still not the best at snowball fights in GW, but I can now at least complete the quests ^^, and well… the best thing they ever added to wintersday were to yuletide tonics. I love those!
And well… I started this post yesterday, and I logged in today, after checking my twitter, and I saw a beautiful surprise addition of costumes! It’s great having them into Guild Wars now, as I was growing tired of my armor.
Now you can buy costumes, using real money, (you’d only have to buy them once though in order to use them on every character on your account), and you’ll wear that, but your armor is still equipped. So you fight with a nicer look, but not with 0 armor 
and they’ve updated the old masks too 
Here’s a picture of the new costumes:
They look awesome, don’t they? This has been one of the best years ever for Guild Wars, with a lot of new additions… I wonder what 2010 will bring
