Arc Fantasy: Skill VS Luck Shot

Posted by rHornbek on November 5, 2011

In the wake off everything else that is going on I have been thinking about another exciting project code named Arc Fantasy (AF).  So not to waist the creative juices, I have been keeping notes and mulling over some of the gameplay specifics for the concept.  Recently I have been trying to decide if the combat system should be based on primarily on Skill or Luck. Arc Fantasy’s combat system is based on the familiar trajectory mechanics of games like Angry Birds, Worms and the original Tank Wars, with of course our own twist which I will disclose at a later time.

An example of a Skill and Luck based mechanic for Arc Fantasy.

In both examples above it is Blue’s turn and he wants to throw a rock at Orange.  Like other trajectory based games, Blue must set the angle (purple arrow) at which the projectile (the rock) will be thrown and set the velocity to determine how much force is applied.  The velocity will also have an effect on how far or near the rock could travel, but to simplify things we are going to assume the velocity never changes in either of these examples, because it is the method of aiming that is really in question.

In the Skill Shot example, the user would only have a very general idea where the projectile will travel based on the angle of the arrow.  The same angle however would always send the projectile in the same direction, creating consistency.  That consistency combined with experience would generate a Skill for Users to choose the best angle for each target they confront.  Despite the limited information given by the arrow, Users would get better at predicting where the projectile will land.  This is the most popular method used by most of the games described above.

In the Luck Shot example Blue is given the full range of information, except the projectile’s movement is NOT consistent.  In the example above (right) Blue knows the shortest distance the projectile could land (lower purple line) and the furthest distance the projectile could land (upper purple line).  The user has no control over where the projectile will land, only a matter of where it could land making it a matter of Luck.


The primary reason these mechanics are in question is because of their effect on another mechanic I am implementing into the game; action specific accuracy.  Users would be given the opportunity to choose between less powerful but more accurate attacks or very powerful less accurate attacks.  In the Skill Shot case, the arrow would get much longer, giving the User a much better idea where they are sending the projectile.  In the Luck Shot case the cone would become much more narrow reducing the possible places the projectile could deviate to increasing the chance of success.

To be clear I intend to take a little from each of these mechanics, but what I am really interested in is what other people think about these two concepts, and which one they would be more compelled by.  I should have more information about the project and its other systems and features soon.
