Game budgets are always a topic of lovely speculation, at the end of the day what matters more is if they make money, I find it especially pointless to argue about it as devs almost never lay down the budgets for public eyes.
Does it really matter if it costs $2b if they make their money back in the first few days?
And just as a reminder, GTA5 sales popped past the $1b mark in the first 3 days
It's just interesting to know what games cost to make - though it makes zero difference to the consumer. Like I said earlier, even if it's £100 for the game - I am buying it, regardless on release day and taking the week off.
