Watching High Score on Netflix, realizing how long it took for character choice to be implemented into video games in a main-stream way, here are a few of my characters of choice:
Street Fighter II: I started out with Chun-Li, moved to Guile, then it's been Ryu ever since.
Mortal Kombat: Began with Sub-Zero and eventually moved to Scorpion.
Mario Kart: I started with Toad, and eventually landed on Yoshi.
