Super Streetfighter IV Arcade Edtion Giveaway (guess a number)

First correct answer gets the key. It's Too Hard!

Q&A:

Question: How do I know there's a key there, it's not a dupe, you're not trolling etc?
Answer: You're just going to have to trust me.

Question: Is this a key from the Alienware Arena giveaway?
Answer: No. I buy keys here and there, and often have them collecting dust for months when I can't decide if I want to activate them or make a giveaway. I took one from Alienware Arena, activated it and the giveaway made me think of my keys. I have two spare, can provide proof of purchase if necessary.

Question: Why not make a regular giveaway?
Answer: I'm confused over the staus of the game in regards to Steamgifts giveaways. The key will say Super Streetfighter IV AE when you activate it, but will show as Ultra Streetfighter IV in your games library. I can't make a giveaway for Super Streetfighter as it was removed from the list of giveaways when they changed the name. I don't want to make a giveaway for Ultra Streetfighter because as far as I'm aware, you don't get all the content from Ultra Streetfighter so it could be misleading.

Question: Should I try for the key?
Answer: If you want, but don't bother once the puzzle has 1 solver. You can assume the key is gone then.

Question: By the time I've read all this text will the key be gone?
Answer: Probably :p
