The change between games can be pretty big if you play them every season a lot.
For example 10 was bad, 11 was good, 12 was shite! 13 I liked pretty much and 14 is new so haven't played it enough to give a statement yet.
I agree that it would be nice if they actually did every September a "yearly patch update" for maybe 10? which would change the default teams, kits and maybe upgrade the graphics etc. But that isn't going to happen, mainly due to 2 factors.
1) The games sell, why throw away all that money?
2) The amount of money the put into making each game. I mean they have the same basic idea, play football. But as the technology to make games gets better, so does the way they make the games and what programs they use. The AI, the moevement of a single limb depending on what you do. The skill sets, goal celebrations, extra stuff like the scouting networks etc.
There's a lot of changes to every game, just like with CoD, the basic idea is the same but there's always a few new maps, a new mission, new weapons, more realistic graphics etc.
And about the controlls, well 9 was different from 10, 10 was different from 11, 05 is completely screwed if you go back and try that game today. It's basically from 12 I think they have found a good default control scheme, 12, 13 and 14 are (almost?) identical. but if that doesn't suit you, you can always change them.
So no, I do not agree with the opening post of this thread but I would love to see the "annual patch" thing happening.
