How can i make a monster-collecting game?



so, I was thinking of making a monster-collecting game, called Shishi ("epic" in simplified Chinese) monsters. or,gigamon. how do I get the courage to make it? should I make it up as I go, or plan ahead? I need help.


Make it up planning is boring "let your heart guide you but take your brain" (I saw that when walking to my piano class)


Thats a great thing to say!


thank you!!!! everyone!!!!!
