No your viewpont is wrong. FFXV dlc episodes were only 1-2 hours long for $15, if you expect anything more than 2-4 hours your delusional
I never played any of the FFXV dlc episodes outside of the Royal Pack that I bought years later on sale. Even then, I only played the Cerberus battle. I wasn't trying to go back to a game that I put 100+ in for more content that should have been in main game.
FFXV isn't the hill to die on though to try and prove your point as that was a shytty release and even you know that.
