The characters are very driven in their strengths and abilities and it doesn't center around the card game all the time. It centers around the themes of fate vs. destiny and mysteries of one's past. I found most of them quite intriguing and enjoyable to hear and watch.
The antagonists are the most interesting since they have their own motives and agendas, so it's a mystery to what their true objective is. The voice actors are amazing and have a lot of talent. I've watched both the English and Japanese versions and have enjoyed both. So, if you want a anime with characters and action, I'd recommend Yu-Gi-Oh!
