There are many flaws in this game that it requires 3G or 4G connection, gps, huge battery backup.
The concept of the game was really good by using virtual reality function.
But by the use of 3G, 4G connection , highly accurate gps it requires very high battery backup.
And for catching the pokemons you have to walk on the roads in parks holding your mobile in your hand. Which increases the chances of accidents.
The games graphics are very good with all original charactristics of pokemons.
