Ah let's avoid MW and BF at all costs. So we should remove aiming down sights, it being a first person shooter, modern weapons such as F2000. Fallout also shouldn't have a possible sprint function either.
Don't straw man. CoD/BF weren't the first games to have the player aim down the sights, nor sprint. That has nothing at all to do with adding things like the F2000, and other guns that just don't fit in with Fallout and it's post-apocalyptic atmosphere.
MW and BF are extremely successful FPS. While Fallout is an RPG, it has also progressed to being a FPS. As such good FPS mechanics should also be involved. Like actually aiming down the sights.
Have you played New Vegas? Iron sights are incorporated. So it sprinting. Again, that has nothing to do with it. Plenty of games have incorporated aiming down iron sights and sprinting. That's not something newly thought up by the CoD or BF creators.
MW and BF also happen to contain a very large assortment of very common military weapons, which in a post-apocalypic society where survival can rely on effective and powerful guns, is most likely wanted. When I said copy and paste, I meant use good common, modern military weapons.
And yet there are even more weapons from the past (1930s-1970s/80s), that fit Fallout's post-apocalyptic setting better than any modern weapon does. CoD and BF's selection in weapons is rather small compared to what could be incorporated by looking at abstract and forgotten weapons of the decades I said. Add in the ones that were used during those years, and you have even more selection. Adding an M4 with simple modifications of scopes, lights, lasers, etc. isn't selection. The weapon isn't anything more than still being an M4.
Ah yes, and I do want MW/BF which is why I had bought them. As well as TES, Halo, Assassins Creed, GTA, Mass Effect, Dragon Age, Farcry.. The list goes on. My point being if something is in one game then, while that is certainly a different game, it shouldn't be avoided. Fallout has other games mechanics too.
Just because it has the mechanics, doesn't mean it should coalesce and become a CoD/BF/Fallout hybrid. That would be the worst. Assassin's Creed, GTA, Mass Effect, etc. are all good games because they're different and stay different from each other. Trying to put them all together would be a bad movie.
