Tend to prefer FIFA to PES, but I only buy it about once every 4 or 5 years. I think I would be physically sick paying £40-50 every year for basically a patch. I did get FIFA 17 last year, and found I just don't pay it anywhere near as much as I would have done a few years back, always annoys me that the AI just increases the speed of the players for the top decisions, as if there are no fast players in the lower leagues, yet even the likes of Morecame or York have the ability to knock it around in near little triangles and keep the ball with ease.
In fact I probably only buy a full price retail game at release a couple of times a year, though I am getting tempted by the new South Park game I have to say.
