Planescape: Torment

• PS:T is a game of dialogue so keep speaking to everyone, including your own companions. This is one title where Friends is a more useful spell than Magic Missile.

• Wisdom, Intelligence, and Charisma in that order are the most important stats in the game as they unlock the most conversation options and Wisdom furthermore increases your experience gain. You can learn to be a Mage by doing a quest in Ragpicker's Square, making the other combat stats even less important. Note that high Intelligence doesn't actually affect the spell slots of The Nameless One despite what the game claims, though it does do so for Dak'kon.

• Lawful is the most difficult alignment to achieve due to a limited amount of opportunities for it compared to Chaotic which counts things like lying and picking clearly goofy dialogue options (like flirting with zombies in the Mortuary). Speaking truths and making/keeping promises as well as picking rule-respecting choices and quest resolutions tend to count towards Lawful. Picking pockets or taking things from people's houses does not affect your alignment, but attacking non-hostile NPCs unprompted does.

• Even conversation lines you've already gone through with your companions before can have new (and often important) dialogue options appear "behind" them if you've learned new information relevant to the topic, so don't automatically assume you've exhausted all dialogue with your companions even if no new choices appear on the initial list when talking to them.

• Make sure you retrieve both your abilities (Raise Dead and Stories-Bones-Tell) by speaking to Deionarra on the ground floor of the Mortuary and Stale Mary in the Dead Nation, respectively.

• Dying is not the end. If you die, don't reload - roll with it.

• Don't be afraid to join a faction. You can always leave them and join another once you've finished all their quests.

• Some generic items worth keeping include a Hammer, a Prybar and one piece of junk. A number of unique items like the Bronze Sphere and a specific person's skull can also come up later on.

• Fell the tattoo artist in the southeast portion of The Hive is worth coming back to regularly, as you progress through quests he'll offer more tattoos and experience rewards. Should you find a certain severed arm, that's also worth bringing back to him and letting Dak'kon translate it when you do. Note that The Nameless One has three tattoo slots, and Dak'kon as well as Annah have tattoo slots as well.

• Morte's teeth can be replaced with new ones. Ingress, who will be northwest of where you emerge from the Mortuary, has the first set you can get. This set can even occasionally be upgraded by "using" it from the inventory menu as Morte reaches certain level thresholds, meaning it can last you the whole game.
