I would like to say that Pokemon Planet Online is a really awesome game, I've been playing it since November of 2014 off an on and I have enjoyed every bit of it.
There are PRO's and CON's of playing PPO, and I am going to fill out some of each for people to get an idea in case they read this thread and decide to try out the game!
PROs
Kanto and Johto completed: Hoenn is complete from a developers stand-point as far as I am aware it's just being held back so certain updates can be performed before releasing the rest of it!
A ton of awesome Pokemon to obtain! (Beldum, Slakoth, Riolu via Casino - Larvitar via Clan Wars - A ton of Elite Rare's to obtain from different maps such as Goomy, Dratini, Bagon, Electabuzz, Snorlax, etc!)
Active Clans! (This is a really good one because a lot of people love having a little family they can join and being able to have fun with a lot of people!)
Wonderful Community:This game has a great community, minus the few spammers but as a Moderator you can be rest assured the job gets done and the community benefits a lot from it.
CONS
Spam happens quite a bit, and it can be bad at times but it usually is easily handled by us Moderators!
You may find it hard to get into one of the more established Clans unless you can establish yourself as a well-dominant force to be reckoned with.
Lastly, the amount of grinding in later levels can possibly turn you off from playing, but a lot of people love the grind as well.
I hope this helps some of you who have noticed this thread make a decision on playing the game! You will enjoy it most likely!
Sincerely,
