Any feedback about the final TB mode? Finished the game once, vanilla version. Is it worth another playthrough?
If you are feeling the urge, and want to do a playthrough with the DLC anyway, I would say it's definitely worth at least trying on turn-based mode. You could always start a new game, try the first island out with turn-based, then decide if you wanted to go further from there.
I personally really enjoy the TB system, particularly with PotD and Woedica's Challenge enabled, which turns all per-encounter spells and abilities into per-rest and removes health regeneration when out of combat. The TB is a bit rough around the edges, and would have definitely benefited from being action point based rather than movement -> attack/ability/consumable based. But the thing is, it's still fun, and it's still an improvement over the RtwP according to my personal preferences. Encounters, contrary to the predictions of many around here, work well in TB mode despite being initially designed with RtwP in mind. And for me, they've simply been more fun and engaging.
Say what you will about PoE II, but they've worked a lot past its official release to add a lot of nice things that take into consideration player feedback. I had fun with it and liked it at release, but these implementations and improvements really make the game shine now.
