Two NPC's are offered. It is a good idea to let both join the party.
 The extra help is handy and they will provide minor amusement. 
 
 If you are ever given a chance to help a dragon, do so, or you will
 miss a challenge dungeon and end story. 
 
 Save games frequently and at different spots. This way if given 
 choices you can see what would have happened if you made other
 choices (ie. some of the deaths can be interesting!) 
 
 Remember to adjust the game level from the camp menu if play is
 too easy or too hard. 
 
 Rest is frequently but not always obviously available. The NPC's help.
