if ESPN came out for PC i woudl consider trying it. Everybody knows EA could do better, but for the PC thats all Hockey has, is EA.
I don't have a mod exactly, but I found settings from NHL Depot for the AI that totally changes the physics.
After I have tried the AI settings NHL Depot suggested, I went from 5 min period games with final scores of 9-6 on HARD to 5 min periods with final scored of 2-1, 3-2, 3-0, realistic, on the hard setting. And the best part, was using the Sens in playoff mode, I went to game 7 in the finals but also triple OT... Now talk about trying not to screw up lol.
edit: I guess it would help if I gave you the settings.
---------------------
Basic: 0 0 5 6 1 2 5
Skating: 1 4 2
Checking: 4 3 4 1 2
Pass/Shoot: 2 1 1 5 3 3 3 3 3 6
Physics: 3 3 3 3
Defense: 4 1
Adjust them to how you would like, but this is the base NHL Depot suggests and it works great I find.
