My firth game was a guitar hero clone in scratch. It was going to be part of a music theory project so I tried to time the notes so that it made sense musically. That w's probably the most difficult part, calculating the note times. But, it was a great introduction to programming games.
Your first game / programming project?
I am not yet finished anything i could call my first project, only some 'trials', may say finished but very small so not to count, of a bit larger bat not finished, so my account of apps is clear - 0
The first thing I ever worked on was a cylinder jumping around on boxes. Actually, I didn't even make it from scratch, I just tweaked and added things to existing examples:
Years later, I turned it into something that looked awful:
Holy hell Comet, I recognize those boxes and that cylinder from one of the DB examples, I think! Gosh, that was ages ago...
That next thing is rather... well, it's kind of terrifying. :P
My first "official" project would have been my game "Coins Galore", for an event over on the TGC Forums. I never quite finished it, but I did learn a LOT in the process of making it. It helped spawn my interest in visual level editors, as well.
My first app, if i dont count the Asymetric toolbook 3.0 i did in high school was a c++ console program that returned the time between 2 dates, at 1 second precision. That monster was like 1000 lines of code long cause i didn't knew stuff for this already existed lol and i wanted to learn anyway. (i lost the code :( )
Then i made a monopoly and 2d chess game in Delphi. Those where kinda good, for a one man project who just thaugh himself programming.
