No its understandable that it takes longer. This isnt a simple HD port like with the Tomb Raider Trilogy. They are basically recreating FF X and X-2. the charactermodels are new, facial animation is redone, all of the graphics has been completely re-rendered and remastered, the music has been newly arranged etc. If you compare the original version to the Remaster version the difference in quality is ENORMOUS. Almost like a shot by shot remake.
So this game shouldnt have come out 6 months ago, thats nonsense. I hate it if people have no patience and want everything yesterday but with the best possible quality. quality takes time. And I rather have a perfect remaster that almost feels like a new game instead of just a cheap usual HD port.
