VG247: Brink was recently delayed into 2011, which is kind of a bummer, because I want to buy it. Could you explain why you felt like the game needed a little extra time in the oven?
Paul Wedgwood: We’re not adding any additional things to it. Essentially, we’re gonna spend longer in the beta phase. Because it’s a really ambitious game, and now that people can see what we’ve done with weapons – the number of weapons, the number of weapon modifications, the number of abilities, the number of items and gadgets – they can see the interrelations between those many components sets up some very specific balancing challenges.
And for Brink, we want to make sure people enjoy playing months after they’ve started playing – or years after they’ve started playing! I think in order for us to achieve that well, we want to have the best possible period of balancing and polishing.
... the push back is for extra polish and balancing tweaks..
