Using JCreator (back in 2006) I made a simple game where you had 4 on-screen buttons to move your "character" (a black rectangle) around the screen, moving over colored disks to collect them. Had some portals and walls. Collecting all the disks advanced you to the next level.
A year or two later I made my first "real" game in VB - A textbased pacman inside visual studio's Listbox gui component. Much later after using Greenfoot for a while, (late 2010) translated it to Java in Greenfoot: http://www.greenfoot.org/scenarios/8243
I believe I continued to make VB games up until I started with Greenfoot (late 2009).
I'm 17 years old and are programming since a bit more, than a year from now on. My first project with Greenfoot was my first project at all. At school we dealt with the turtles from Mik's tutorial, but in lessons, when I was finished earlier I added my ideas so far I could do in this time. At home I worked at it more, but later I became the idea to make a tank, with two classes. I never made something like that before (I programmed not very much at all before, because I hadn't known it really), so I tried and it worked. Inspired by my successes I added more things, so that it become a real game. I watched Mik's tutorials on youtube, too. As I discovered this website, I decided to load it up here. But I waited first because It wasnt to complete enough. It isnt't finished at all, but the main things and the base are done. Later some friends began to create music for it (that isn't very far from now in past). They are working on it still, from time to time. In lessons we began to programm on GUI's with the java-editor and with blueJ. That was intersting, too and helped to concentrate on ptogramming, nit on have to do so much graphics for my game. If Tiny Tank is finished I begin to program a 3D-world maybe. My programming-skills aren't such big, but I am willed to learn. I think the math wouldn't be the problem. . . So the next one is invited to write his story!
PS: Try the Tiger in Tiny Tank, and please comment!
I remember make a few small things in YoYo Games' GameMaker, but nothing real significant. In 8th grade, my friend taught me how to use Flash and I made a couple things in there. The first real game I made in Flash was one where you played as a rectangle that walked around on crudely drawn ground and a bunch of other things like water and moving platforms. There was almost no coding to it since I just stole all of it from my friend.
The first thing I made with Greenfoot was late last year, when my APCS teacher introduced it to me. It wasn't really a game, I made a StaringWombat subclass of Wombat that would stare at a StaringLeaf (subclass of Leaf). If there was another StaringLeaf, any normal Leaf, or a normal Wombat (which you could place any in game with the keyboard), they would chase after a random Wombat, Leaf, extra StaringLeaf and eat until there was only one StaringLeaf left. I wanted to make something mildly creepy, and related to the tutorial (which I barely looked at).
My first game is still in progress ^^ It's Procaryota, a shoot them up: http://www.greenfoot.org/scenarios/7845
Soon a big update! ;-)
My first game was a little game in gamemaker, hardly good enough to call a game. My first game on greenfoot was a binding of isaac clone, and I worked quite hard on it. It was almost finished(I say almost, but I hadn't gotten the world generator working), but then I lost my USB stick :P. Then I made a RTS(A failure), and then a platformer(Don't know how physics works in programming :S) and then I made "The robots-Kill them before they spread", which you can play on this website.
My first game, without using Mik's tutorials, was a very simple game where some turrets shot at a car which the player controlled.
