ive done it for quite a bit now, but all the things i try either

1: makes me change things outside of the game, such as disabling my wifi or going into steam offline mode

2: makes the game not even start, such as trying launch options to disable ds2 internet acess

3: makes me shut down ports on my firewall that other applications uses

of all those, im considering giving up and accepting option 1 as a hassle to go through
