Hmm I think I'll go from present backwards to past:
I published 3D-Tetris 2 more than a year ago and I announced 3D-Tetris 2.1. I never published it yet, but the project is NOT cancelled. Work just goes on slowly and I'm working on other projects at the same time. But I do realise that the upgrade from 3D-Tetris 2.0 to 2.1 takes longer than the upgrade from 1 to 2...
At some time inbetween I made I small game "Black and Red" for the 100 Lines Contest. I sucessfully finished it, but I didn't win anything.
Before that time, I tried to make a jump-and-run game "Rudi the Tin" but after I showed the screenshots in the Showcase (yeah at the good old times the "Projects" section was still called "Showcase I"), the comments of the community convinced me that I was no good level designer or graphic artist and that the project failed (of course I'm not angry to anyone, I'm rather glad you told the truth, it's often difficult to realise how bad your own creation is). So I started to make said 3D-Tetris 2 and thanks to Spike who made the graphics for it

Before that time, I made 3D-Tetris. It helped me to learn about programming and it's the first project I sucessfully finished.
Before that time... well, I once tried to make a poker game, which failed (I later realised that the methods to recognise the hand were totally inefficient). And I tried to make a big economy simulation game, which failed of course, as I totally overestimated my skills. I never published any of that projects, but I still have them on my hard disc xD
