Ok, after finishing first act I can give you my quick summary of the game:
Started the game on easy difficulty level. I wanted to play thief-swordsman so I have spent points on strength, speed, and then on constitution. Later in game I have added to dextrity and strenght mostly, and about 20 in intelligence for basic spells. After adding 6 points to melee combat I have found out that thief can only unlock two ranks of this skill. Melee combat proved to be usefull at the begining, but later I have switched to ranged attack, shot and run tactics, with my companions tanking enemies. Didn't know which other skills to level so i choosed armor (useful), identification (not very useful, since there is a spell that does that), and some thief skills, but didn't used those much. Perception could be useful, but then again you can find secrets on your own. Levitation and Raise dead, and probably sixth sense were most usefull spells for me. And seals! Seals are great! Especially those with lightninh. Keep the powerful ones for harder oponents. So, the story was great, and fights not so demanding as some would say (after talking to everybody in town it's probably best to grind some levels at cemetary, and the dragon-rock surroundings). And the atmosphere is amazing! Great game! Five stars as for me.
