Games take more time and effort?!
Rubbish, especially in this case. Games have way too much oversight and micro management. They had the characters and the story already done for them. The assets simply had to be remade to a modern standard. Absolutely no optimisation is done anymore and you used someone else's engine which already did a massive portion of the work for you.
IF this game took longer than expected it was because you spent so much time figuring out how to milk as much money from it as possible.
