In DQ8 there is a Monster Arena side quest. It was kinda boring and too RNG dependant to me to be fun. I aproached the Dark Prince demo with caution, but go surprised on how much fun I was having the game. Yeah, the monster doesn't do exactly what I want all the time, but is limited just for the arenas and is much more managle with all the config options. I may try a challenge run of this game in the future with the flexibility for team customization it provides.
