Well I hope there is a trainer that will be made for use on private games in non-sandbox mode!!! EA
There isn't any 'private mode' per se though, okay you can invite friends into a region, but that's still all server managed and monitored.
yup they do work.
Thanks for the confirmation. I also just saw the other thread saying that they're in the manual.
Some people reported that they don't work though. Well, we'll see when the game arrives (which probably will be during next week...)
