First of all, I want to say I don't usually go for Let's Plays over playing the game (Very rarely) but there are a lot of aspects of this game that I think make it better to just watch the Let's Play.

Jojo nKnB is a very quirky TBT JRPG. it has an adventure componenent and a battle compoenent. Niether have aged well or were really the best design to begin with. The adventure segment is wandering from left and right with the occasioanl door or path above or below. IT serves to pace the story and plaer through linear, static gated events (wandering into a battle into a certain spot of the map and then unlocking another area, etc) so this makes the game 'wandery' and makes it feel somewhat aimless.

The second component is the turn based battles, which are overall very classic and similar, but there is a twist or two: You dont actually win all the battles and sometimes you need the opponent to even flee and approach them again later... So in addition to the attack command there is a think, command and another option as well that can let some of the people in your party trigger these events. Final result is a TBT JRPG battle system in which you never know if you're supposed to take out an enemy or you are supposed to 'trigger' them in some way to end the battle. I found this a deal breaker and super annoying because you'll just get locked into battles you cant win and you never know which is which.

So between these two bits, teh game is 'wanderey' and the combat is 'fumbly' and after playing the first quarter or so of the game I decided to switch to a let's play and just appreciate the games story and lore elements based on the franchise... (In this sense, it's quit good) There are a lot of elements pulled right from the original source material! (And there few bogus non-canonical things also thrown in for whatever reason)
