That's not really a great justification because you could apply the same for PC vs consoles. "Could you imagine what would happen if those console players could compete with PC players?". Take away the auto aim and it would be a slaughterfest. Also, you should try FPS on tablets. It's much better yet still portable.
But like I said in my edit, if that's the only problem then just buy that Gameloft controller. It will cost about as much as buying CoD.
I know what your saying but there are other factors.
When im playing on my vita I know everyone else is on the same system and having the same set up as me. They experience the same frame rate and the screen size etc etc.
I have played MC3 on my iphone. I was pretty impressed with it for what it is but the phone was always to small for me to get the true precision I wanted out of it. I found that online without the heavy auto aim on, it got pretty frustrating. Even with it on I would still get annoyed after a couple of games. I know other people out there I am playing against are using tablets and I would imagine its a lot easier to play on a tablet that the tiny iPhone screen. Il be getting a nexus 7 this weekend and if I see it on sale I might pick it up on that and see if I fair any better. However that imbalance does reduce the fun for me. I like people being on a level laying field.
Add to this that gameloft stick in some stupid stuff like buying kill streaks and that kinda ruins the game on another level. I would not be surprised if they were in MC4 as well.
Nova 3 has the same issues.
Anyway CoD BO
def plays better and is more fun (to me at least) than MC3.
Touch screens also add other hurdles like only really being able to put two imputs at a time. Its very hard to aim and move and do anything else bar spray and pray. You can keep aiming while firing off very short bursts to keep your aim accurate for example.
Im definately not one to go LOL touch controls as I have happily played plenty of games on my iPhone but they really are not that suited to fast fps's. The best the did was dead space and thats a tps with guns that fire in single rounds so you could tap to shoot. Worked really well. A CoD like twitch shooter gets a lot more limited.
That gameloft controller is also a joke. It looks horrific, Uncomfortable and is really expensive (last I heard anyway) and if you play on a phone where will you place the phone itself?
