About 3-4 out of 10. The strategies were good in duels such as Yugi's duels with Doll/Strings and Pandora/Arkana, especially with the fleshing out of the system through the Battle City rules making it's internal logic a lot stronger, though there was still too many overused Shonen cliches such as Jonouchi/Joey having superhuman stamina, something as hax as Ishizu seeing the future amounting to
's lifelong accomplishments on the scale of worth, Yami Marik just being evil for the sake of evil and it being made apparent that Yugi would win from the start because of protagonist plot armour.
Still an improvement from Duelist Kingdom due to not having as much Heart of the Cards bullshit in it's finale, and the best arc of the series (original at least. Didn't watch anything after that other than dropping GX 5 episodes in) but far from high quality.
