Ok so having been playing this again and having had a few requests for Jenkeys gameplay settings, heres mine. I think these play brilliantly but you may want to tweak.
One thing I've noticed is that somewhere along the line, Jenkeys gameplay tool has stopped working, so the app won't run in order to tweak ball speed etc. However if you go to the plugins folder and find the gameplay tool config (basically a txt file of sorts) you can open that an edit values directly.
Heres my settings with explanations:
shot.power=100
Some people have this a little higher but this is the default value and it works well for me, you do get powerful shots with this.
ball.speed=130
I played with this value for ages, 125 was the usual, but 130 is great. Gives the ball a bit of zip and helps eliminate the floating feel in combination with ball weight.
ball.weight=145
This is the most essential value. This gives the ball a very real feeling of weight. The original game felt like you were kicking a balloon, this makes it feel a like a football. This combined with the above makes the game feel like its got a bit of pace, the ball a bit of bounce and makes goals and passing more satisfying.
AI.Slider=1
So the default for this is 0, if you want an easier game of sorts set this and the next two values to 0 and it plays more like the vanilla. This way it gives you a little space on the ball around the CPUs area and the CPU doesn't chase you down as much. With this set to 1 the CPU is much smarter. When you play a ball into the channels the CPU won't wait for you to receive the ball, they will go for the ball. They will close you down and track back. Their forward play is smarter and for me I see much more variety of goals from them. AT 0 they tend to hit weaker shots. This is a challenges and can make the game a bit frantic at times but its good as it makes you switched on with the ball and using it properly.
AI.Level=1
This is almost the same as above and really needs to match the above value. I think this gives the CPU a bit of welly. I play on professional and it seems to work best for that as the CPU will still make mistakes but can play a bit too, rather than just whacking it on top player or superstar for a challenge.
AI.enforce=1
I have this set to 1 too and I'm pretty sure this value gives your team mates a boost too in order to keep things balanced with the CPU.
Motion.speed=102
100 is the default here, i pushed it to 102 as it makes the players motions a bit faster which in turn with the other values makes them more mobile rather than slow and ponderous. It doesn't completely eliminate the feeling of a lack of pace to players but it definitely helps. Just small increases to this value make a big difference.
GK.speed=150
Been playing around with this value and settled on this. Again 100 is default game setting but boosting it gives the keepers more reaction to situations. You can still score long shots, they ant infallible but it helps with the CPUs close range 1-1 efforts.
AI.optimze=1
This adds more player movement, aggressive defence and more general active AI on the pitch.
AI.remove.script=0
Putting this to one, removes the cheating CPU apparently. Cant say I've noticed much but I've kept it off for now. Need to play with it more.
Ball.curve=100
Default value but lowering it and highering it gives more curve to passes. I don't think this needs touching personally, theres lots of curve in the game.
Ball.accuracy=100
I had this at 140 originally, its to help your passing be more accurate, but its too accurate and in football you need that loose passing. I found it more difficult to lay on a pass into space with higher values or just knock the ball into space. So i keep it at default with passing assist off.
Goalnet.rebound=150
I switch between 110,150 and 200 with this value. Makes the ball whip around the net as it make the nets more elastic with the ball. The ball at higher values will fly back out of the net more, at lower values when the ball hits the net it just sits there. I think 110-150 is a good balance as you tend to get the best of both worlds. At default the net is less lively and a bit flat in a lot of scenarios.
Gravity=100
Not touched this, does weird stuff!
Player.match.point=100
I have no idea what this does.
Pass.support=100
Much like ball accuracy this is tied to passing and has the same problems so keep it at 100.
Player.responsiveness=140
Default is 100, i boosted this to 140 and find it excellent. Your players react to situations better and it seems to help eliminate the cheating CPU, where your man just won't react to a stray ball or missus an interception he should get.. It works 95% of the time.
And thats that. Im having a blast on this. Yes the players can feel a little stiff at first as we are so used to the motion capture of today but honestly, this game has so much depth. The players are individual, the teams play a decent tactical game, keepers are good. Yeah the AI cheating sometimes lets it down and the CPU variety of shots (although improved with jenkeys tool), add in the Kitserver stuff, customisation on PC and this is a must have game.
Heres some youtube vids i recorded, quality a bit ropey but hey ho:
With the version 3.2.1 that
