If you like playing a game as a free player, Chrono Tales isn't for you.  Heavy cashers dominated the game and this leaves free players with nothing to do but bot monsters and quests.  The carfting aspect isn't that interesting since you have to grind for the materials and the pets are nice, but not really useful unless you spend cash upgrading them.  In all honesty, Chrono Tales should be listed as a play to win game.  There's nothing interesting to do as a free player and there are plenty of other games that will let you compete in events like Siege War without having to pay with real money to do it.
