Gothic 2
You can edit your Gothic.ini file (back it up, first) to use Qucik Save and Hot button for Potions.
Read the books on the Pedistals, there are at least 10 differnet ones which give you XP for reading them the first time.
Besides the Mages, Mercenaries and Paladins guilds, which you MUST join one (can only join one of the 3) there is a 4th Guild, Thieves, which you can join alone with any of the other 3 guilds.
You learn Pickpocketing, Lockpicking (learnable without joining Thieves) and Sneaking (learnable without joining Thieves) plus they give new quest and is the only guild that does not Manipulate you, i.e. you must do this or that before I will help you.
It is a little difficult to join, as a hint it is done by NOT turning in 2 petty criminals and doing 1 slightly dirty quest, nothing evil, this all happens in Korinis.
There are 6 chapters which have an effect on some quest or actions, 5 on the island and last you do not return.
If you join the Thieves guild learn Pickpocket if you use this skill in chap 1 you only get 50xp, if you use the skill in chap 2 75xp, chap 3 150xp, chap 4 250xp, chap 5 350xp and chap 6 450xp each use, a huge differnece.
You can only pick a person once during the whole game, except if they travel to different lands, i.e. 3 possible lands New World (where you start the game), Old World (Valley of the Mines) and Last Chapter.
So if you meet about 4 or 5 people in chap 2 that leave the Old World and come tothe New World, you can PickPocket them in chap 2 and then again in chap 3 and if they return again to chap 4 the Old World you can Pick them again.
This means that most people you want to leave till chap 5 before you PickPocket them because most NPC do not move from land to different land.
