One of the things that made the original computer game--Hot Death UNO 1.1 written in Visual Basic--worth updating was that it made us laugh. How did it do it? With the sardonic wit evident in the new cards? Sure, I suppose, but what really did it was the computer players.
That's what made the game really fun. It was a one-player game, but it rarely felt like it. Lively computer players voicing their opinions about their current situation in the most hilarious ways, quoting goofy movies, arguing, and generally making the human player part of a great group of pals.
For this ticket's criteria to be successfully met the computer players must have visible avatars that speak by way of text messages. The computer players must have "personality", preferably unique, with each player having their own tendancies toward gloating over attacks, whining over taking damage, partaking in banter / chants / etc., and should partake in the classic HDU mantra: "One Good Draw 2 Deserves Another!"
