Which time?
First time Action Masters drove me away, Robotech brought me "back" to G2.
Stuck around for Beast Wars initial figures, got bored and wandered off.
RiD brought me back, specifically Prime + UM = OMEGASUPERPRIME. Car bros too.
Armada looked terrible, so wandered off again. Cybertron Sideways + news of the live action movie brought me back and this time it appears permanent.
