I see it as more bad than good. On one hand, it's a cool game and it's nice to see a PS3 exclusive get noteriety, especially from an indie company.
On the other hand, it promotes digital downloads which the gaming industry will use to suckerpunch gamers. Devs have already cut costs by doing away with instruction manuals and releasing unfinished games. Physical media is the next target. DLC, season passes, etc, it's like being in a casino. The house always wins.
While games like Journey and The Walking Dead are creative and refreshing, I wouldn't want see a gen where all good console games are only available via digital download let alone released in episodes.
