Originally this game was very disappointing. You couldnt do anything without it crashing while: catching pkmn, trading them for candy, naming them, or fighting gyms.
Since the latest (legendary birds) event Ive noticed the servers are still in disarray if not worse. Although you can now catch, name and transfer your pkmn, the game constantly kicks players out during gym fights. And places where there used to be no connection issues now have significant issue connecting to the server. Causing players epic proportions of disenchantment with the game.
Also, Im personally offended that there arent more customization options for the character model. Specifically, the hair is a generic anime style hair. And there isnt any representation for curly, wavy or even bald heads of hair. Even beards should be an option, considering that most people who play this game are adults. Additionally, within the cannon most gym leaders are also adults.
The lack of representation to different types of people shows a lack of consideration for the player-base. Hopefully Niantic will add this easy addition soon.
However, when its not being temperamental and ignoring the racial exclusion the game is a fantastic way to get out there and interact with a mostly pleasant and friendly community and the world.
