Earlier in the year they removed the trial offer. Now it’s returned, but worse than before.
This is similar to my experience. A few games came and went that I was interested in but not a single must have and I don’t think I ever did more than install a game and try it for 20min and then lose interest. I would just keep signing up over and over for $1 and sometimes when I’d cancel they would even refund me my $1. It was a bizarre system. I don’t even honestly think I was abusing it either be because I got about a dollars worth out of it every month.
