My favourite room is the smash bros room and the wifi trio (wifi, battling, and breeding rooms). Mostly because I prefer wifi battles other than showdown however I make my teams on showdown, play with it on ps a bit, then try and get it on oras. And people always have a pokemon you want or they're up for a battle. Smashbros because I love smashbros and as much as I do with pokemon. The smashbros room is home to many diverse players. All of these room contain nice people so don't be scared to drop by they're always welcoming!
My favorite room is probably Lobby. Every time I go in there within seconds I receive some of the most outlandishly hilarious PMs. From "Drink bleach and die mod scum." to "I have been physically assaulted by a drunken lazer-eyed octopus help me!" I pretty much get them all. Plus the room is always chaotic so I can usually pick out some killer comedy.
I used to hang out in the Lobby, but I've since discovered the Writing Room, and I don't want to join anyone else's room. It's usually chilled, unless I'm posting riddles, then the salt piles up.
I've made more than a few friends in there. Plus, any trolls are swiftly dealt with. A good time all around. Now, if we could get the Smogon server back up and running...
The Survivor room is definitely my favourite room on PS. Really fun to play & host survgames, great community, often-times a rather relaxed environment (when Spieky and PyoroLoli aren't online *flees*) and so forth.
I've also been in the Game Corner room for the past few days or so, and I'm really enjoying it there too!
My favorite room is the rmt room, I get my teams rated all the time and I am becoming a better team builder. Also, the auth there are really nice, especially fleggumfl the driver, which is also voiced in the ou room btw.
