Well there's a lot of these text-based online games. Some are fantasy (KoC, DT, LoL, RoT) and others are futuristic (SFCG, QSSE, BNT). Most only take a few minutes each day to play. Some have a kind of alliance system that allows groups of players to get together and have advantages. I don't play all of them, mostly I stick the to simpler fantasy "click-based" ones. They are easy to play and get started. If anyone's interested in doing more than NationStates, tell me.
