I don't think I've agreed with
Wyrmlord more than I have done in this thread. It's scary! But yes, binary non-combat skill checks are all well and good, but they are so awful from a gameplay perspective that any cRPG that features them in abundance while lacking severely in terms of combat (Planescape: Torment, Fallout, Arcanum) is trumped by cRPGs with even a half-decent combat system. It also doesn't help when a game lacks party creation, which even Baldur's Gate allows in multiplayer mode. This is why you'll find lots of old-school party-based RPGs on my list but no Arcanum, Fallout or even Planescape: Torment.
And we can take this one step further:
If we were to remove the distinctions between combat and non-combat situations and say they are all just an abstract collection of skill checks of all kinds, then which one has the more depth? Which sort of game has the more complex in-depth skill checks, combat or no combat?
Let's compare fighting Jierdaan Firkraag with talking to the Practical Incarnation.
People debate heavily on how to fight Firkraag, and
in this link, they suggest using Breach, using Lower Magic Resistance, using Magic Resistance to pre-set the enemy's Magic Resistance, using Project Image, using Polymorph Other, using the Gate spell, using Traps, attempting Feeblemind, attempting a Finger of Death, attempting Quivering Palm, using Protection from Fire, using Harm, and so on. And which one of these spells you attempt depends on how the combat encounter plays out, so you have to change your plan once something does not work out. On different successive attempts, the same fight could be harder or easier depending on how everything plays out. You could be on the verge of turning the dragon into a squirrel, but Firkraag turned towards Edwin right on time, so now Anomen has to try Finger of Death on him.
Now, the Practical Incarnation. If you have an Intelligence or Wisdom of 21 or more, you merge his soul into your own. If you don't have an Intelligence or Wisdom of 21 or more, you are out of luck.
I am okay with Torment being called one of the greatest games of all time, and I even agree with this notion. But if we can put Torment in that class, it's surprising that people say BG2 can not belong to it. Everyone's entitled to their opinion, but what is the logic behind a game with binary problem solving trumping a game with multifaceted problem solving?
