I'm here wondering if it were not for the pokemon, will this game be famous or people would not be ready to go out in search of coins? 
Pokemon just gave the market an interesting idea. And if projects like IZETEX can expand and improve this idea, than why not? because before the pokemon there was one game with exactly the same gameplay and and few people were interested in it. that's why it seems to me that if it were not the Pokemon, then IZX app would not receive attention.
