One of my friends would always talk about it and play it a fair amount when we hung out. He loved the ascii version of the game, so at the time it didnt appeal to me as much.
A few years later when I played games like TOME and unreal world I gave CDDA a try and really liked it. When I first started playing it I though the game was super hard - those shocker zombies sure were hard to kill with a brand new character attacking them with a coffee pot.
300+ hours later of playing the game you start to feel like the game is too easy, and purposely limit yourself to make it more interesting: start with a shower victim, dont invest a huge amount of points into dodge etc. In my opinion the fun of the game is trying out different strategies and builds and seeing what works, then learning along the way. It feels great to have a good run with a character, but once you have knowledge of how the game works you start to feel guilty and resort to purposely avoiding certain builds or strategies to keep the game interesting.
