I'm not saying its difficult..... I just want point out that the concept of "dying".... getting a message prompt "do you want to continue ?"... clicking yes then waiting for the game to reload so you can try again has got absolutely jack shit to do with difficulty.
After all you don't "Die" in DoA either.... you get knocked out.
Death is just one way of the game acknowledging failure.....
Building a game where you cannot die does not mean you cannot fail. And with that put into perspective, think about how many times you failed in The Reboot compared to how many times you fail in PoP2 or 3.... the number is pretty much the same. PoP (2008) simply doesn't waste your time with it.
