I used to play years ago and Hoover has brought me back. I seem to remember a bit of a fuss about multiple accounts per household/IP addresses due to potential for cheating. Having seen me play, my partner is now interested in having a go. Is this going to create issues if there are two accounts being run from the same home (albeit different devices)?
Can I highly recommend that you play on different game worlds. As there is strictly no cooperating there would be no need for you to both play on the same gameworld (2 players, 17 game worlds to chose from)
