I've spent the last week or so putting together a fairly comprehensive plug-in for Phaser in the form of an isometric (axonometric and dimetric to be precise) renderer for Phaser. Not wanting to stop there, I decided to go the whole hog and port over Phaser.Physics.Arcade to the new renderer by adding in an extra dimension.
You can get the plug-in here: http://rotates.org/phaser/iso/ - the page also contains a working example so feel free to view the source to get a feel for how it works. I'll be creating several more examples in the coming days and weeks, as well as improving the plug-in, fixing bugs and so on.
As of yet, I am undecided as to whether to embark on trying to create an isometric equivalent to TileMap (with Tiled importer) but if there's enough interest I may see what I can do.
Enjoy, and I'm looking forward to seeing what you do with it!
