I can't say much for PoP: WI. But if you like the first one a lot, you will probably like the second one (but not as much). I didn't like Sand of Time, and found the second one a little worse than the first.

Basically, there are more actions... but still, I think they are quite boring, because the Prince is... well, just a prince, so sure he has some fancy jumping around attacks... but to really do the trick, all you need is block, dodge, and counter.

Some bosses (or a boss) are ultimately cheap, and that fight is really just a routine sort of block, dodge, run away now, attack, must dodge this, can't block this, repeat. (Something like that...) (Well, there is a way to end the story without facing that boss, but...)
