Remasters from a game that came out 10+years ago (PS2 era and older) are ok. (Wind Waker HD, Grim Fandango HD, Oddworld New n Tasty)
Remasters of last gen games (PS3/360) are fine as long as they come with significant changes, better performance, extra content, a collection pack, lowered price and in some cases never came out in certain parts of the world.(GTA5, FF Type 0)
Remasters of games that came out no later than 5 years ago with little changes other than "Uprezzed to 1080p, and now running at 60 fps", and sold at near full price when you can get the last gen versions for less than a softbuck is bullshyt. (God of War 3 remaster)
