Sadly BioShock 2 hasn't performed quite as highly with Take-Two noting that sales are "slower than expected," but it's still "profitable" for them.
They "conservatively" expect a "long tail" of sales for the open-world romp of Red Dead Redemption, much like the extremely long tail of the Grand Theft Auto series. Rockstar release the first DLC for the western adventure this summer, adding more co-op.
Take-Two also admitted during their investors’ call they were worried about BioShock 2's reception, given the rather surprising love of the first game seemingly coming out of nowhere. Critical reception and sales allayed those fears, despite being 'slow'.
