Naturally, I had to get this game. I played some of the other games and loved them, and already a few days into playing and I can honestly say I enjoy this one.
Now some basic tips and info for those who also take up their smartphones searching for adventure:
1. WATCH WHERE YOU ARE GOING! Don't trespass on private property and risk getting shot.
2. Always play with a friend. It's safe and also it makes the game more fun!
3. Don't be afraid to walk! It's good exercise (that we all should've been doing).
4. Servers will be crashing a LOT! This is what happens when a game of this magnitude is just released. Be patient and know it will get better.
5. Your phone will die a lot. The game will be drawing from wifi and data (depending on which you use), as well as tracking GPS, running as a game, and using your camera. That is a lot of work your little smartphone is having to do.
6. BE CAREFUL WHEN NAMING POKEMON! I'll admit, I enjoy naming some things like "Buttsworth" or "Richard Dixon" but please remember that while we are adults, there will be children playing this game too. Try and be respectful.
And that is all I can really write about on the matter, as it is, you know, a few days old. I do highly recommend the game (It is free to download after all), and it provides a neat new way to interact with your environment.
Good luck!
