When I say, I built my computer, I mean I designed a PCB, laid it out, etched it, assembled it, then needed to build a display board to output to a TV, which was another several months of design, etc. And when I had all that... then I had to start writing some sort of software for it! (EG: I had to write software, build an EPROM programmer (because they were expensive) burn EPROMS ..... all to get to the point where I could start working on making an implementation of BASIC!
So, when people complain that "kids can't hack on iPhones" ... well, I think its silly. You buy a Mac and you get a fantastic IDE and development platform for free, etc.
To the OP: Congrats on making your game! It looks very professional. Keep at it!
Having to build a computer (with your definition of building, of course) as a young kid... God, that's the only Heaven I want. After those two years you can send me to Hell.
Buy a Mac to hack on iPhone? I don't think that any IDE is so costly if you develop on any other phone.
Or if you're a startup, you can receive all Windows stuff for free ;) (so you don't have to pay)
That said, I'd happily pay £500 to not have to use Eclipse, but each to their own.
You must have gotten a lot of pocket money when you were 14, then.
