I have a pretty cool idea for a portal roleplay, but I need at least 2 other people to help me come up with an interesting story and to come up with NPCs like wheatly.
So far I've come up with the idea that there are five test subjects (only 5) that are normally testing through aperture. This is an alternate reality from the game, so this is when aperture was still up and running with hundreds of test subjects still alive. These five subjects begin to find glitches in the system, eventually being able to communicate with one another, and they each have to find a way out on their own side. It's a pretty decent idea since it keeps the loneliness feel that portal has while still allowing for a decent roleplay atmosphere.
Like I said, I'm looking for others, so this story is still up for change.
