Oh gods... what is my least favorite game? Considering I tend to enjoy so-bad-it's-good media, it would have to be something mind-numbingly dull and average.

And that's how I felt when I played the PS1 Master of Monsters back in the day, though I'm not sure if it really is lackluster or if hex-based strategy was just very not my jam at the time, or a bit of both. Anyway, I remember the English voice acting being cheesy as hell (affectionate), so at least it has that going for it.
