I have three disk versions, two of which I can find and do use. I also have a Ubisoft UPlay version. I use them all, on three different computers, that way -IF- I can ever talk my sons into playing, we can do multi-player on the three machines... All three computers have to be running the same version and same mods, but that is easy enough... grand fun - for me, anyway... the boys don't like being sunk, whether they take a convoy or a sub...
- so the only way I've been able to get them to play last couple of years is in co-operative mode...
I highly recommend a person have multiple copies..
