This is definitely an MMORPG I'm looking forward to. Ever since the early days of Everquest, no other game satiated my MMO needs. WoW and Guild Wars got pretty boring fast, and I didn't play them for longer than a month.
The oldest online game I played was Ultima Online, still have some good memories there. I have the best memories of Everquest though; did tons of non-stop raiding, I was very hardcore. I don't plan to be that hardcore in Vanguard though, hopefully it will still be an innovative game in this crowded genre.
