I've started playing this one and it feels like a love letter to D&D veterans and CRPG players who cut their teeth on BG back in the days.
The character creation alone is almost as involved as pen and paper and frankly the lack of information regarding some of the classes (I'm not too familiar with the Pathfinder version of D&D) makes the whole thing a bit challenging.
I did start with a halfling rogue but the fact that the guy has to wield a specific weapon type to be any good (i.e. to add his dex bonus to damage with weapon finesse) makes me feel like he is too much of a one trick pony.
The game itself reminds me a lot of BG but more than that it feels like what BG would be like today given the nicer visuals and some pretty cool additions (camp management for instance which reminds me of Expedition Vikings).
I've barely scratched the surface but I can already tell the game does succeed where Sword Coast Legends failed (Pathfinder Kingmaker remains true to the old real time with pause formula without turning into an action game à la Diablo which was the biggest problem with Sword Coast Legends).
My only minor complaint is that the game does take into account dialogue options to affect the alignment which feels a bit odd because saying the "right" thing shouldn't make you shift towards good if you're lying and don't mean it (something which any self respecting villain would do without a second thought). I can see why it's working that way but still I wish they would have added an option to lie (well nothing prevents you from assuming your guy is lying in which case I guess the alignment system is more like a reputation meter).
I'm really liking it so far. I'm thinking of restarting with a wizard (probably with some rogue thrown in). It's hard to fight the chronic restarter syndrome plus figuring the right build for a character is definitely part of the fun.
