The only disappointment was that the sequel is not on PC.
general, which you get by completing quests or just killing enemies;
strength, which you get by killing enemies with melee weapons;
skill, which you get by stealing or killing enemies with ranged weapons;
and will, which you get by killing enemies with spells.
The experience spending system has three categories: strength, skill and will, and the categories' spells or boosts can be bought with the category specific experience as well as with general experience.
The character you'll be playing on is called the Hero of Oakvale. The thing is, you can have a satanic or devoted alignment or anything between it, and it will affect your appearance as well the range of spell levels you will be available to have. Logically, commiting good deeds will make your alignment more good and commiting bad deeds will make it more evil. One thing that helps you maintain either your good or evil alignment is the availability to choose between evil optional quests (a massacre against villagers, guards etc.) and good optional quests (protecting your allies from a massacre or something). Even though there aren't many optional quests where you are given the chance to choose between good and evil, it should be somewhat easy to maintain your alignment with additional items like "dark" or "bright" armory or tattoos that give you an alignment modifier(- for evil, + for good).
Another unique feature of the game compared to many RPGs is that you can own or even rent a house/houses. They can also be upgraded for an additional cost, and then they will provide more rental money. You are also able to have a wife(or even a husband) who can come and live with you in a house you own. You can also decorate your house with trophies, which you get from quests, and they will increase the value of your house(thus increasing the rent) according to the value of the trophy.
The quests have three categories: core quests, optional quests and quests that are received from somewhere else than the quest board. Core quests are ones you have to complete to progress with the story, optional quests are, well, optional. And the third category consists of another category of optional quests, of which some of them can never be fully completed. They just have a different category because they have no quest card. Most of the quests also have a chance for a bonus called a boast, which increases the amount of gold earned if the boast is completed, however if you fail the boast you will instead lose a part of the reward according to the amount of the bonus reward.
The game is not at all just about fighting and completing quests. You can break into shops or other peoples' houses, and if the guards catch you, you will be fined. If you refuse to pay for your crimes, the guards will attack you and you can not interact with the people of that town. You can always escape, but if you get back in the town before a specific amount of time has passed, they will start chasing you again. If you get back after the time limit has passed, though, everything will be the same as it was before the crime. If you aren't into crimes, you can always spend a nice night out at the tavern. Consecutive beer drinking will result in a blurred vision and in a worse case, vomiting or passing out.
All in all, it's a pretty awesome RPG with a whole lot of cool features that make it stand out. Anyone with any experience of RPG games should try it out as it will most likely not be a disappointment. 10/10, the best PC experience for me so far.
