After playing the first game, I wanted more. When I heard about a sequel, it was too soon to be a completely new game and I realised it would be just a rehash of the original.

The first game shows how well things can be achieved and they can definitely improve on the original as well as giving a more open environment. I'm happy to wait provided the result is a good one.

I downloaded the demo of Arkham Asylum. It's very good. May buy the full game at some point. Cash permitting.

Batman: Arkham Asylum was one of 2009's most celebrated titles - so it's little wonder publisher Eidos is readying a Game Of The Year edition for release later this month.

Standard fare, right? Well, not quite.

As revealed on CVG yesterday, this particular GOTY comes will fully functioning 3D - which will no doubt tempt a whole bundle of gamers back to witness Joker tormenting his captors.

Here, CVG quizzes Sefton Hill, boss of developer Rocksteady, about the release, the game's lasting appeal - and the small matter of Arkham Asylum's upcoming sequel...

So... Why 3D, and why now?
It's an exciting new area and we thought it would work really well for Batman. I saw the tech just as we were finishing up Batman and I was immediately excited by it, especially as it worked on both console platforms and didn't require people to buy any new kit.

The opportunity came up for a Game of the Year Edition, so we decided that we wanted to add something special that everyone could enjoy rather than just a re-release with new box art...

How well does the 3D work - and can you talk us through the process implementing it in the game?
The TriOviz system adds depth into the screen as opposed to making objects jump out as you might see with polarised glasses in something like Avatar.

However overall the system works really well, adding to the experience while remaining inexpensive in terms of rendering cost. This has meant that we haven't had to adjust or remove any features while adding the 3D to the game. With some clever trickery from the code team, we've also included all the in game movies in 3D as well.

What would you say the 3D elements bring to the game that it didn't have before?
The 3D works really well with Batman because we have the lead character positioned in such a prominent position on screen, even by 3rd person genre standards. This means you get a great sense of the depth between Batman and the environments as you play.

Do you share Sony's confidence that 2010 will be 3D's breakthrough year?
I think there will initially be a market for 3D but I don't see it making a major breakthrough as soon as 2010. Some of the expensive technology required in the top-end glasses makes 3D gaming not really much of a spectator or social sport so there's always going to be a bit of a barrier there.

The good news with Batman is that you get two pairs of glasses in the box so you can watch a friend play and choose if you want the Batman or Joker themed specs...

If I hadn't played the DLC previously, what would you say were its real 'wow' moments to make it irresistible?
One of the team's favourite parts of the game was the Scarecrow challenge map which is now available to all as part of the Game of the Year edition. This is undoubtedly the toughest challenge in the whole game - one hit and you're dead. If you want to prove you're the best at FreeFlow combat then try challenging your friends at this. I personally have never got past round five.

Batman is undoubtedly one of if not the game of the last year. Do you feel that because of your success, the pressure on for you to perform with your next project?
Yes, definitely. But it's a good pressure. We're all really excited that people want to see what we're up to next and we really want to surprise people again.

I'm really excited by our next project and I promise we won't let anyone down. Unfortunately I'm not allowed to say any more than that.

Will the next Arkham Asylum also be in 3D, or is release this more of a one-off experiment?
No comment.

Do Microsoft's Natal and Sony's wand hold any interest for a studio like yours? Are they just for casual games?
From a personal point of view, I'm really excited to play any new technology and see the new directions that gaming is expanding into. To be honest I don't see this replacing traditional gaming though, just complementing it.

I think there will always be a market for people just lazing around on the sofa, relaxing while playing a game. At least I hope there will be - as that's how I like to play.

Two-Face will appear in Batman: Arkham Asylum 2.

The news came via a slip from Kevin Conroy, the voice-actor for Batman in Batman: The Animated Series. A report on ComicBookResources says that a "fan tricked Conroy into revealing that Two-Face was a character in the upcoming 'Batman: Arkham Asylum' sequel" during a panel interview.

He added that the game would be "really, really dark".

"It involves a lot of the villains and it goes to that area - it's that dark," he said.

Realising his Two-Face slip-up, Conroy tried to backtrack by saying, "There's a very complicated cast... a lot of villains are in it. I'll just leave it at that!"

Oops. Bit late for that. So now Two-Face is all but confirmed, who else do you want to see taking on Batman in Arkham Asylum 2, CVG readers?

More Batman: Arkham Asylum 2 voice actors have outed their work on the sequel, following this morning's slip up that Two-Face will appear in the game.

Actor Maurice LaMarche is next to out his Arkham Asylum 2 post, stating in an interview; "I'm about to go in and do Mr. Freeze for Arkham Asylum 2."

When asked to give a taste of what Mr. Freeze will sound like, LaMarche claimed, "To tell you the truth, I think, contractually, I can't. I've got to keep it under wraps.

"He's out for blood right now because, err... I can't tell you the situation, but he's actually somewhat a sympathetic character within the framework of the game."

That's Freeze and Two-Face on board for the sequel then. Next up on the PR naughty list is actor Stana Katic, who posted on her Twitter: "Just recorded a character voice on the next Batman video game. Never did that before. Helpful hint: plenty of water and pineapple slices."

She followed up the Tweet with this, before quickly removing both messages: "For those who were asking: I'm voicing Talia al Ghul, the daughter of Ra al Ghul (played by Liam Neeson in "Batman Begins")."

That's at least three villains confirmed for the follow-up then, not including the Joker himself.

TBH, since I've played the game, I've not gone back to it. Hence I'm gonna miss out on all the DLC.

They should release DLC say within three months of the game coming out.
