Before I started my current job, I was always very curious about making games. Not in any serious sense, more like, "Wow, I bet it took like twelve people just to make that guy's head explode when I pressed that button."
And then when I started talking with and getting feedback from developers, I realised, yeah, it IS a lot of work as I'd always suspected... actually, it's a lot MORE work than I suspected. If you're talking about even just a simple flash game, think of everything you have to take into consideration; various browsers, operating systems, and so forth, and working on making your game compatible with all of that. I can also tell you that the few times I have been talked into helping beta or bug-test something were NOT fun; it was my job to BREAK that game, and that basically involved doing everything over and over in every way I could think of, trying things on various computers and browsers to make sure everything was copacetic... no thank you, SIR. I'll stick to writing about it.
I think articles like this are great, though, because so many gamers either don't know or care just what is involved in making their favourite games. (Thinking back to the FF7 remake butthurt here.) You may be making a game, but it's still a job, and if you want to make something halfway decent it's a freaking HARD job. I'd really recommend anyone who thinks making games is fun and easy just crack open any toolset (RPGMaker, NWN, Dragon Age, etc) and try to make a compelling hour's worth of an experience. It really puts things in perspective.
