A game of logic, Which statue lies and which tells the truth?

A text adventure from a game I played.

In this game, a man is stuck in a dream and two individual go into save him from it.
These two individuals need to go into find him and return him to the real world. They search the dream,
coming across a whole manner of various artworks. Ranging from mordern, to classical.

The two individuals come eventually across three statues. Each unidentifiable from the rest, apart
from a word engraved onto each statues arm. 'Alpha', 'Beta' and 'Gamma'.

Only one form is real, the others false.
The real one will only speak the truth.
The others will only speak lies.

Each statue began to move and bowed down.

"Please" said Alpha. "You have to get me out of this nightmare. I am real."
"Stop lying" said Beta. "Alpha is a fake you know. I am the real one."
"What a load of crap" Gamma said. "Beta is fake. Everybody knows I am the real one round here."

The three statues silenced, and returned to their original form. The two then began to wonder which one was
telling the truth. And which was telling lies.

Only one form is real, the others false.
The real one will only speak the truth.
The others will only speak lies.

Is it...

>Alpha
>Beta
>Gamma

I will try: I say Beta is real.



This is a variation of Smullyan's Knights and Knaves problems is it not? Anyone who likes this sort of puzzle might enjoy those if they have not come across them

Correct.
