On my bus rides to/from work, and while practicing guitar, I have been really enjoying watching Twitch streams. As a lifelong gamer, it seems strange to enjoy watching people play more than playing games myself, but that's where I am in my life, and I'm OK with it. The entertainment value is really superb. Some of them have amazing broadcasting talent.
Amazon now owns Twitch.tv, and included with your Amazon Prime membership are some Twitch perks. You have one subscription to a twitch broadcaster of your choice that you can use every month. (a $5 value). This directly supports the Twitch broadcaster financially, and it looks like some of them are making some serious money as full-time streamers.
So here are my favorites (You can watch clips from their streams even when they are offline):
Jam Jar - www.twitch.tv/tehjamjar This guy is from the UK, has a great voice for broadcasting, and is funny as all hell. He's the one I'm currently using my Twitch Prime sub on. Seems like a really great guy IRL, too. He plays a lot of "PlayerUnknown's Battlegrounds" (PUBG). It's a King of the Kill type 3rd person survival shooter in which the map constricts, forcing players toward each other, where only one will ultimately survive. He also does some very funny role-playing in other games.
Smak - www.twitch.tv/smak This guy plays Rainbow Six Siege, but lately has been playing PUBG, which is really fun to watch. He's a very serious gamer, and hates to lose, but also has fun at it.
Silent Sentry - www.twitch.tv/silentsentry He's a nut! But he was born to do this. When he plays a shooter, he expertly narrates what's going on at a million words a minute, but he really excels at Role Playing. Check out his clips as "Lil' Squirt" on the GTAV role-playing servers. I laugh my ass off when he puts on his rap concerts.
darbian - www.twitch.tv/darbian The current World Record Holder for Super Mario Brothers Any% and Warpless. Droll wouldn't begin to describe his speaking manner, but he still manages to be engaging and fun. He adds heart rate monitor telemetry to his broadcast so you can see his heartbeat spike as he approaches a new record. He's currently trying for the Super Mario Lost Levels Warpless WR.
CarlSagan42 -www.twitch.tv/carlsagan42 He seems to only play levels created on Super Mario Maker and Kaizo Mario, but he's damn good at them, and pretty funny. He's a research scientist by day, so often he gets on some pretty good side topics.
Summit1g -www.twitch.tv/summit1g This guy is getting rich at this! It's amazing to see the subscriptions and donations pour in as he plays. He's somehow able to be cocky and humble at the same time. I only watch him when he plays PUBG, but he also plays a lot of Counterstrike.
M1ndr - www.twitch.tv/m1ndr He plays DayZ, which has incredibly long boring stretches, punctuated with some intense battles. I prefer to watch his YouTube videos, which he expertly edits down to the good stuff, complete with music for dramatic effect.
Let me know if you've found any good Twitch streamers. And be sure to use your Amazon Twitch Prime sub.
