Of course, anyone who finds the game less challenging than you is "cheating" in various ways.
And why is the way to make the game more "realistic and difficult" to download an unofficial skin which obscures a large portion of the games data? That's not realistic. Only signing players from your village, only signing 4 foot Andorrans, those aren't 'realistic'
"don't use player search" well of course that makes the game more difficult. Put Bukayo Saka in goal as well, that'll make it more difficult. Did you know you can make Call Of Duty more difficult by intentionally not shooting enemies?
So you make the game more difficult by just using a default tactic, and then not doing any tweaking or actual football management...
so that's don't make a tactic, don't download a tactic, don't use player search, don't look at player stats, don't sign good players..
Sounds realistic.
It's cool if people want to set up their own challenges and restrictions but it's annoying how the usual response here to people saying the game needs to be more challenging, is essentially "have you tried not scouting?" "Have you tried intentionally not using effective tactics?" or even boasting they've lost 10 matches in a row or have never won a trophy or something, as if that's a sign the game is hard and not that a) they've purposely hamstrung themselves in a way that is not realistic to being a football manager or b) they're actually just rubbish at the game
You can't sign a "16 year old wonderkid from Peru" as a League 2 side in the game. And if it was possible IRL, clubs would be daft not to explore the opportunity even if it wasn't one of their "club visions"
