Fair enough but I would say that BF3 and BFBC2 seem pretty close. Minor tweaks added jets and helicopters from what I have seen while playing it. So the people that have BFBC2 and bought BF3, are they short sighted too?
BC2 and BF3 are very, very, very different.
the only things they share are that they are both FPS games and have a similar graphical style. That is to be expected seeing as how they are both DICE games. Even with the same genre and a lot of similarities, gameplay and the entire feel is infinitely different.
Starcraft and Warcraft 3 have similarities - they are both RTS, have similar gameplay styles, they have similar graphical styling, but they are very, very different games. The similarities are down to both games being made by Blizzard.
Compare MW2/MW3 to BC2/BF3:
Different engine - BF3, true, MW3 false
Different graphics - BF3, true, MW3 false
Different weapons - BF3, true, MW3 true (sort of)
Different maps - BF3, true, MW3 true
Different vehicles - BF3, true, MW3 false
Different sounds BF3, true, MW3 false
Different gametypes BF3, true, MW3 true
Different movement animations - BF3, true, MW3 false
Full ranked dedicated servers on PC - BF3, true, MW3 false
now that is a handful, it doesn't scrape the surface of the raft of extras brought in with BF3, but only manages to miss very few of the MW3 extras
The views from others on websites from all over the net echo exactly what I am saying - the game is the same as MW2, it is stale, it is not an improvement. The only people singing the praise are "professional" reviewers, who claim that the game is the freshest, newest, most revolutionary game ever made
