Well, I've been playing Kitsu Saga for the past couple of weeks, and I've got to say, it's definitely one of the most boring games I've ever played.  My first clue should have been that the game comes with it's own in-game AFK combat system.  You read that right.  The game encourages it's players to bot their way to victory.

Slow, tedious gameplay aside, let's talk about the skill system a moment.  Again, ridiculous is the only word I can use to describe it.  As your character (who is most likely going to be AFK) kills monsters, they accumulate "energy" which is used to learn skills and increase said skill's power level.  One collection of skills that the characters learn are called "Inner Focus" skills.  These skills, in particular, rise in cost at an alarming rate.  Take a look at the table below.

Level 1: 600e
Level 2: 1,875e - 312.5% increase over cost of level 1.
Level 3: 3,450e - 184% inc
