I just found out about PMOG, the passively multiplayer online game, from Russell's blog, he sent me an invite and I'm already loving it!
I love games but never wanted to get into a MMORPG like World of Warcraft for fear of spending way too much time on it, but this is great, it just translates all the hours I spend surfing the web anyway into a game experience! It's still in Beta, but it looks pretty cool.
Tell me if you'd like me to send you an invite! Come and play!
