From the PlanetPlaystation.com feature editorial:
"Independent game development has managed to rise incredibly over the years, gaining popularity across major home platforms all the while retaining its indie credibility. What makes these titles so outstanding is their reliance on old school design, high challenge, inventive gameplay, or in some cases, all of the above. Indie games are unique and oftentimes inviting, presenting players with an appealing experience that sucks them in and keeps them returning to it. Just look at Super Meat Boy, one of the most popular indie games in recent memory, and easily one of the most challenging."
