I was debating on downloading it and checking it out. I play PWI which is also free to play (spend rl $ for gold to buy stuff, etc...in game). But GW2 I enjoy even though I've dropped some coin into it due to restricting high level mats needed for crafting was implemented awhile ago due to bot farming...hopefully they'll add more nodes for the 2-3 items back in that they currently have in a couple map areas.
I have the old PC version of NWN but never really got far into it. Maybe I'll give it a go. Right now it's the last leg/part of the Scarlett storyline in GW2 which is due to end in a couple of weeks I believe. I prefer the fights on the marionettes in Lornar's pass vs the wurms in Bloodtide coast (they are frickin hard to beat....way harder IMHO that lornar's). Finally hit 8k achievement points yesterday (or was it today?). But it's challenging, esp. thei dungeons in there...need to go with people who know the different paths in them. Hard stuff starting at lvl 35 lol. If you are in GW2 I think you can find me as metalmike.8346 or as one of my chars - any first name (Scary/Sneaky/Cutey/Pain/Quickshot/Siren/Madness) and Kometh as last name. I am on Sanctum of Rall server/world as well.
