Motion Blur is nice, but it's really just a gimmick. It's not going to make the game any more fun if it's turned on, and it's way too intensive to be played by casual players. Most people get into indie games because they just want the core game play and originality witch was present in earlier eras. IMO most games these days care mostly about graphics and looking as hot as possible.. Just gimme a new n64 Zelda or Snes Mario and i'll probably be playing them a lot longer than Gears of War.. I'm not saying that I loathe all new games, just trying to get the point across that indie games are part of a completely separate universe in which I care nothing for high end graphics. Pixel art, 8 bit sounds and chiptunes ftw.
Dude, it'd be nice if you'd let everyone decide on their own what styles and effects they're relying on to make their project come to life.
I think your way of seeing things is really limited. I don't want to re-do the old games over and over again, I want to see '2d games' going through a revolution in terms of gameplay and visual styles.
If you'd give me the N64 Zelda or the SNES Mario I'd gladly hand them back to you, cause I've played those games 10-20 years ago. That part of gaming is already history and we see too many remakes being done right now already anyway.
I don't think that most gamers get into indie games because of the core gameplay that was presented to them 20 years ago, I think they're in for the innovation and because the chances that we see something completely new are rather high when we're talking about productions that cost under 200k to produce.
Ash already summed it up nicely - MoBlur is a really important effect and is way more than just eye candy.
