Man, again with this crap of telling us to use the evil guy to torture the good guys... this is horrible, why do they do that. I don't care for getting 15 less coins, this is too immoral. I just go in with Tyranno and pretend he's in Battle City instead of Marik.
The main question is why do they make story events this way to please freaks like you when the great majority of players properly side with the good guys.
Hmm... I'm afraid I don't know. Why don't you try asking Konami? If you have already contacted players around the world (the majority of us) about this, then I imagine that it should be a simple task for you to also find their opinion on this matter.
What good is there in a "variety" where what you as a player are doing is 🔥ed up. It's not simply playing as the villain, it's playing as the villain where the consequences of winning are comiting abominable sins. It's not like the typical duel world duel where villain just faces hero in a casual duel. Noticed the 5D's story events don't have this crap anymore? Thank God.
