Well if you think about it, it is the same thing over and over again. Shoot a person rinse and repeat. It's just a matter if you can not get tired of it.
Thats a litle simple.Thats the same as saying every racing game is the same,or at least all F1 games are,and all GT games are..just go round and round in circles right?
All BF games are same too I guess? Some vehicles,some guns and shoot.
Killzone games are all the same too.Run around shooting in MP and shooting the Helghast in SP.
Get my point?
The thing is,yes,diff locations,diff perks,different way to set up classes,diff killstreaks,customizable characters,diff backgrounds and patches,diff guns etc etc.
Whether the guns are diff or not is subjective. They may be for you,but there are plenty of vids on YT going through differences in the guns.
I think its fine they release a new CoD every year. Who wants to play the same game for 2 years waiting for the next one? Too long,every year for CoD is fine.
Besides,diff dev teams make one every second year and try to out do each other,Infinity Ward this year and no doubt Treyarch next year..yeah..I look forward to seeing what Treyarch can do on the PS4.
I wish they would release a GTA game every year,as long as standards are kept high ofcourse.
