Basically I've come across a few games that use this convention, and I'm curious on how its done and want to implement it.

Something similar to this;

This video seems to have accomplished it really well. There are a lot of pretty bad implementations of it too.

I just want to know where to start, what to look out for, any tips or advice.

Cheers

The term you're looking for is called billboards. It's basically a simple quad (two triangles) rendered like any other 3D-Mesh. Depending on what you want there are some differences, this page seems to cover a few variants.

That isn't all 2.5D though - only the characters look like billboards. The rocks and the walls are all 3D objects, as seen by their changing shape when the view is rotated.

Yeah that's basically what i'm looking for. Just the characters/enemies are 2D yet all the surroundings 3D. That video illustrates what I'm trying to do exactly..

Now that I know the terminology for it, I'll take a look around at some resources. Thanks!

Edit: Wow. Looks tricky.. this should be fun...
