And gbp3 is an absolute insult. Off-peak, you can get a ticket for
unlimited train travel throughout Greater Manchester for less than
that, for example. gbp2 is too much for a Zone 1 single, IMO.

I'm born and bred in Rochdale myself and I've had many GM Rail Rangers,
but I would still say that a One Day Travelcard (which is still paper)
or even Oyster Pre-Pay capping is better value due to the huge network
it is valid on. The equivalent to the One Day Travelcard in GM is the
System One Bus and Train ticket which is 4.00 or the Bus, Train and
Tram Daysaver which is 6.50.

An all day System One Bus only Daysaver (GM) has now just gone up to
3.50, whereas the equivalent in London will still only be 3.00 from
January (with Oyster).
