I just had a look at some of the other fantasy games to see if they were worth playing.
The Mirror and Mail are just horrific. You can have multiple teams with subs and you can sub players prior to earliest kick off without incurring transfers.
So basically, if you plan on trying to win, you have to check and change your team every single day there is a Premier League game. Who has time for that?
Even Sky have gone over the top with theirs. If anyone is playing it you can make a captain change within a game week now which is Sat to Fri. So you have to try and aim to have a captain playing on the Saturday which you can then change for the Sunday. However, if you transfer the captain out this doesn't incur the free captain change. So say if you have a captain playing on the Sat, you can transfer him out for someone playing on the Sun and then make another captain change in midweek. Ugh.
Edited to say you can make a captain change within a gameweek, that's what I meant
