Quoted from Rarehero:If the Multiball gets progression save, thus removing the roadblock...at the very least it will be more fun. I eventually just went thru the game with the glass off to see what was going on...and it's really cool to flip to the other side and get the Leonard Nimoy (Sentinel Prime) voice overs...it's a nice change of pace from the Optimus monologues. This won't change the unchangeable flaws and broken promises, but will make it a better game for sure.
The game honestly isn't unbeatable as it is. I have beaten optimus mb several times as an autobot. Last game I played, I beat optimus and megatron mb both, and no other modes I have also been in the optimus prime only rut so I know how frustrating that is. But I've managed to beat optimus in 3 times out of the last 10 games I've played.
I will own this pin again if my room expansion happens.
