Hell yeah, great to see Mr. G&W in this. Just like C.Olimar788 said, he's just insanely well realized. And if you think of Smash how I do, more of a celebration of Nintendo and video game culture than anything, he became an immediate necessity after being included.
I'll never forget unlocking him in Melee over at my cousins house. My cousin was so disappointed, he wanted someone "cooler". I was amazed and entranced, and I mained him for a long time just to spite him with bacon. He taught me about an entire Nintendo era that I had no idea about at the time, and the amazing part was he's so well realized, he taught people that stuff through his moveset alone.
G&W for life.
