I really enjoyed Travian for about the first 5 minutes I was playing.  But by about the 6 minute mark I had used up all of my resources and had to wait 15mins or so for my first building to be built.  From that point on it was a series of waits, and then spurts of spending, and then more waiting!

What really ended it for me though, was when I passed out of the 'safety' period.  From then on, other villages could attack me.  And attack me they did!  One particular user stole from me over and over and over and at every opportunity.  I may have missed something, but every effort I made to defend myself was easily overrun.  In the end, playing the game was pointless because I never had enough time between attacks to build up an army or improve my village.

Here's hoping anyone else who tries it has a little more luck than I did.  Overall, really didn't enjoy the game.
