What's Needed To Participate In The Tabletop RPG One Shot Group?
This question has come up a few times. I have answered it countless times. That is ok though I understand there is a lot of information out there to sift through so this is going to be my guide to what is necessary, recommended, and preferred.
Most people run games over Google + Hangouts. So you will need a G+ account. A YouTube, Roll20, and many others are recommended though. If you have a YouTube account you can broadcast your games. If you have Roll20 you can use grids and many other tools. There are many other resources out there but those are the most common.
Now it is mandatory you have some sort of microphone so the other players can hear you. I personally use a cheap Logitech Stereo Headset H110 (microphone headphones combo) that sells for about $10. Many people use Blue Snowball (do not get the ICE CONDENSOR SNOWBALL), and Blue Yeti (most recommended) because the sound quality is a lot better than built in microphones on laptops and the cheaper microphones out there. Headphones are important because without them you will pick up sound from your speakers and make the experience tough on the other people in the game. This is one of the more annoying things when playing a game. I have used my iPhone ear buds before and it does the trick just fine.
Next up is a camera and there are people out there who won't allow a player in their game without one. I am not one of them but I know of a few who require it. A built in laptop camera should be sufficient enough but if you really want to there are some quality webcams you can pick up. I recommend the Logitech HD Pro C920 because it offers up to 1080p but works just fine at 720. Anything above this I feel is certainly overkill for live plays.
So if I was just getting into everything I would focus on the microphone above all else. When playing in an online game that is the most important aspect. The Blue Yeti is going to give you the best sound quality but may not be necessary if you are just playing in a couple games a month though.
