Terry's traits are probably easier to wrap ones head around as it's more or less a come back mechanic. Well to me any way. Between Terry, Lucario and Joker I feel like their unique gimmicks aren't too intrusive to the way I prefer to play Smash. Although Terry does have the fighting game inputs like Ryu as well right?
Ridley being the way he is was an absolute God send for me. He's relatively simple in execution and with that my mind is at ease to get really comfortable and creative with him. His off stage game is so good and so fun! Grabbing people mid air, carrying them under the stage, waiting for them to tech, jump up for a froward air to smash them into the underside again while I comfortably fly back up to the top is just so good!
I like that complex characters exist for those who want them but even someone like Hero is a bit much for me just because of the vast options involved. Ryu, Steve, Rosalina & Luma along with the Ice Climbers are too much for me. When someone that is a little more straight forward is revealed I get pretty happy. Though admittedly as long as I love the character it usually doesn't matter how they play, I learn them super willingly.
This doesn't apply to Diddy Kong however. Diddy is my boy! I love me some Diddy Kong! In Smash however, the banana, the peanut pop gun and rocket barrel just sour me on the character so much. I don't particularly hate DK64 but I don't love it any longer like I did during my first play through back in the day. The rocket barrel and peanut gun originating from DK64 irks me. I want a Diddy that uses only his natural born body to attack, not all them God danged monkey gadgets!
When it comes to Donkey Kong however I just want him to toss around barrels as a projectile. It's what DK does!
