A new time waster browser based game just came out (I think maybe even just yesterday--not sure) called
Lord of Ultima. It's free to play, but does have some micro transaction elements if you choose to use them (more for automated queuing when offline and other management stuff). Anyway, I'm just now looking into it to see what it's about. It looks almost like an MMORTS. I'm on World 3 (NA EST). My player name is Swad and my city is Swadville. Hit me up if you check it out and let's see if we can get an alliance formed. I'm not sure how how multi-player works as you get a week of immunity before you can be attacked so you can get defenses built up and get things rolling.
