When to drop friends
You'll find it easier to find the robots in abandoned towns, so I'd keep them for a while
Forum Discussion
I just hide them and then once in a while check if they've played recently. I usually give neighbours a few months, sometimes longer for really long time neighbours or really nice towns, but I do sometimes get impatient when a new event hits (or they have crappy towns and never visit :wink: ). I think a few of mine are currently on holiday, a few are playing but still haven't up-dated to the SciFi (probably because they never read the forum and have automatic up-dates disabled).
