First of all, I liked this game very much. I could only play it for a day because my Yahoo! version doesn’t run very well, but I like the unique concept, and perhaps I will get myself a better and up-to-date version sometime soon.
What really surprised me, however, was the introduction:
“It’s 6.20pm on April 14th, 2006. […] Tonight is your twentieth birthday. […]”
That was on the spot! I did, indeed, turn 20 last year on April 14th. I think I will remember this game forever just because of this coincidence. 
And just so that this topic gets some purpose, one question: What could be the fastest way to build a good relationship with as many people as possible in Kudos?
Did you suspect clever AI at first?
