Same with watching 11 men from various countries/regions kicking a ball about under the name "Brighton"? It's only a game.
If anything, getting annoyed at a computer game, where you are in control and your own errors **** things up makes more sense.
I just won the domestic treble with WEST HAM on LEGENDARY. Lost 3 games all season.
And I've just started my online seasons thingy and won my first 10 games.
I've not once felt the computer or opposition had suddenly improved. If it is doing it then it's certainly not that difficult to beat...
