As everyone has said, greed is definitely his most defining thing first and foremost, but Wario being so driven is something that defines him to me. He gets his ass beat in SML2 and decides that if he can't steal a castle... he might as well go on a journey to get rich enough to own one of his...
Honestly a hard choice. I love the ugly ass style of Wario Land 4, and 1-3 have an interesting style themselves. VB is crazy though, they look so high quality. You can really see Wario's muscles in action.
Me and a friend during a VC did discuss the idea of them doing a Odyssey or Bananza style game for Wario, which I hope is a genuine possibility. Anything to get Wario some platforming+fighting action.
I'll be the troublemaker this site needs. You can call me Troublemaking Care. Or Troublecaring. I don't know. Will post when I set up my trouble factory.
Despite the fact I managed to finish Yakuza 0's climax battle mode, I played like one in Yakuza Kiwami and immediately noped the fuck out. Felt like a war veteran having flashbacks, but instead of being about a war, it's about horseshit challenges
