Help on current ways to work with 2d sprites on unity3d?

Hello Unity Users!

I’m new at unity3d and scary as hell. I was used to write all game code by hand, and now I do have to change my mindset to get a good grip on Unity.

So I would like to ask, what’s the current line of work to make 2d sprites on Unity?

Thanks for your time!

I do know it is not hard to find answers for this on google. I’ve been reading some articles myself. But I just want to know the current de-facto way to work with 2d sprites on unity, on this end of the year of 2013.
