If you are curious and interested in Indie game development then there are quite a few sites with useful and informative info. Here are a few sites that are well respected within the Indie gaming and development community:
gametunnel.com - Independant Game News, Articles, Reviews, Previews, Interviews, and Forums
indiegamer.com - great set of forums for Indie Developers with questions. Great community for beginning developers and veterans alike.
indieinformer.com - Indie Game News, Developer News, and Industry News, also contains developer blogs.
These are just a few of the sites that are out there with information related to the independant gaming scene. Perhaps none of this was what you were looking for but hopefully some of these sites and the info they contain will be helpful to you.
Unfortunately I can’t give you a straight answer at how viable indie game development is, but at least with all of these sites you can get in touch with some of the developers out there (Indie forums are great for that!) and find out what kind of success and hardships can be expected within the scene.
Personally I think the Indie scene is a great place to be extremely creative, unfortunately there is also a plethora of unoriginal clones flooding the Indie scene that are being passed off as “Casual” games. This unfortunately hurts the scene but at the same time, thankfully, we have developers such as Positech (Cliffski), Chronic Logic, Cornucopia, Hamumu Software, and Robinson Technologies, Outside The Box Software, and just to name a few, who create games with much more originality and PuppyGames, who also show much more care for their products than some of the other developers out there that are just looking to make a quick buck off of rehashed clones. There is still a lot to like about the Indie scene because of the developers mentioned (there are also many more that I haven’t mentioned but I can’t remember them all and it would take some time to list them ) But thankfully they’re out there. Well, hope this inspires you a little.
