For me it feels Cod is going the wrong way. It is not what it used to be anymore, things are getting to future based and the remaster is just bait to try and sell more copies of the game.
At first they wanted to release a Modern Warfare bundle wich was an amazing idea but after the many dislikes for Infinite they changed the whole idea and added Cod 4 as an extra meaning they noticed that Cod needed a boost.
Many people were in love with Cod 4 and by adding it to the new Cod could boost the numbers but for me it is not enough to buy the game
