I think the market and viewpoints of games ingeneral isshifting slightly, inadvertedly allthough with such breakthroughs such as the Internet and such, Developers can keep in contact and produce games at a more reapid rate indirectly. (such as websites looking for translators, or simply sending data instead of manually shipping carts*1)
Though with the emerging of the internet, it does have its own inheirantly good sides and bad sides too, seriously the internet has given birth to alot of titles that started off as a labor of love and became dedicated games in their own right, just look at Minecraft, Runescape and Cave Story, the latter of which was singlehandedly made by a Japanese man for over four years, it's popularity sparked when he even shown a gesture of good faith of allowing people to translate it so people outside of Japan could witness the game too.
Fast forwards a few years and it's been picked up by a developer to produce for the Wii and DSiWare services...with somewhat debatable changes that either didn't add much value, or just simply annoying, like swapping the main character with another main character with only a few lines of different dialogue, compared to the boss rush, id have to say that the Boss Rush was the better adition. Also the original creator didn't have much involvement, but the good thing is that it's being remade for the 3DS by Nippon Ichi and he'll have a more prominant involvment this time.....though i wonder why they're avoiding Japan...do they think he's sold out his original product or somthing?
Back to the internet, the Apple iStore accepts productions basically ANYONE and can practically set theirown prices as they see fit, coupled with the financial crisis, it makes games alot more widespread...though like diamonds, theyre so rare in the rougth.
I think what they mean with garage and indy producers is 2 different lines of thought, a Garage producer is a single person in a faceless mass with a small chance of succeeding either with low production values or a severely limited idea that would look smart if executed properly.
Whereas Indy producers would devote months building up their games, perhaps composing their own jingles and sounds, physics and such, then finding a prospective company who will stand behind it and help act as a funnel to provide it to the customers.
1* - How did developers make games, debug them and translated them before the internet came? specialised devices? cracking open a Japanese game then copying it a hundred fold after tinkering with it? pretty curious.
Nintendo pretty much has full reign on their WiiWare/DSiWare services since they have to go through PEGI/ESRB first, then accepted by nintendo after checking file sizes, whereas Steam, the PSN network and the XBL Market places has less restrictive methods on the games they sell...it probally doesn't help Nintendo that their downloaded games are non-transferable except for a few incompatibally inclusive games that isnt allowed to be sent to a 3DS.
