Even with the release of games like Demon Souls, Dark Souls, and Bloodbourne Spelunky and Super Meat Boy Artistic Merit
Personally, this is the best thing about indie games: the ability to actually become artistically viable. There is a great push in videogames to be taken seriously as an art form and be heralded alongside the Oscar winners and Booker prizes shortlist. There are some mainstream titles that do manage to achieve this, for example, Bioshock and the The Last of Us spring to mind, however, when I first played Journey and Limbo I had the same sensation the first time I read or saw The Godfather; this was art in its purest form: an expression of the human experience that touched me deeper than any Halo or Call of Duty game could ever do.

The reason many of these indie developed games can be taken so seriously, is because they have more freedom to be innovative and to broadcast their own individuality. Big budget games usually have to stick to formulaic designs because they are made for massive budgets and have to sell millions of copies to turn a profit (Call of Duty, Assassins Creed, etc). Indie games are usually made for little money and even the smallest sales figures are considered a success. These games, like Limbo, Journey and Ori and the Blind Forest, have the freedom of a smaller budget and a hell of a lot of creativity, which leads to them being the complete antithesis of the mundanely repetitive FPS genre.

Innovation and Retro Paradox
This is an interesting point about indie games as they seem to contain within them a paradox, as they can be massively innovative like Journey or Minecraft whilst at the same time having a retro feel with the likes of Spelunky and then you get some that are both at the same time, as with Limbo. I believe this paradox has bled into the world of mobile and browser gaming with the various King games and gambling games on Sun BingoKickstarter
