Play! Framework 1.x supported creating an IntelliJ IDEA project by the command: 
However while Play! Framework 2.0 is in beta that command does not work**.
So how do you get your Play! 2.0 project to open in IntelliJ IDEA? There are few different work arounds. Especially regarding integrating sbt.
However I have a quick way. For this to work you need both Play! 2.0 and Play! 1.2.x installed.
Create Play! 2.0 project:
(I am assuming it was a Java project that you chose)
Rename project folder:
Create Play! 1.x project:
Create IntelliJ project:
Move IntelliJ files to Play! 2.0 project:
Remove 1.x project and rename 2.0 folder:
Now you can open IntelliJ and then go to file/open project, then find and open helloworld/helloworld.ipr.
There will be some issues such as libraries etc but this a good start. For further tips try these suggestions.
** As of 11th of January 2012 it is not present in Play! 2.0. I fully expect Play! to create an idealize, eclipsify, netbeansify etc as soon as 2.0 is stable.

   And as I predicted, with the release candidate of Play 2.0 there is now again in buildt support for Intellij.
Simply type play idea to create the IntelliJ module. More at github.com/playframework/Play20/wiki/IDE
