Bwahaaahaaahaaa! Abandon all hope, ye who enter!
It's a lot of fun... really. However, I *do* remember playing Travian before showering in the morning... then after showering... then during breaks during the day... then before dinner... after dinner.... before bed... when getting up to go to the bathroom in the middle of the night...
It can be very time-consuming. It can also be a lot of fun. I know Felix, Johnny, and Sever played for a long time, and have played out some games. I gave up... I wanted a life again...
The good news is that you can play for a while and then quit if you feel like it.
There are also a lot of web resources that analyze things in the Travian world, like good plot spaces, competition, and so on.
