I don't hugely care about online, but what I've seen on the next gen remake has been impressive, though not quite enough for me to double dip yet
What I really want is a single player expansion with more heists in San Fierro and Las Venturas
But I put 50 hours into the PS3 version, when the PS4 version is the right price, I'll happily do the same again. For now Unity and Dragon Age are keeping me perfectly occupied though
