Redhotsonic

redhotsonic is a British YouTuber and respectable ROM hacker within the Sonic scene, who has been active since 2003 and making videos since 2015; he is the primary inspiration for Matt's Sonic content, and is in fact Matt's favourite YouTuber.

His YT Content
As far as content goes, he splits videos into three main series: Throughout all of this, though, he manages to keep your attention and create a light-hearted atmosphere which is enjoyable to experience. RHS' kind demeanour and friendly nature shows itself pretty much all the time, and this allows the viewer to engage with him on a personal level.
 * Let's Try - RHS will pick a mod or a ROM hack and briefly play through it, giving his opinions as he goes. The lengths of these videos can vary, but not many go past the 10-minute mark.
 * Let's Review - RHS reviews fangames and ROM hacks, some of which come from the previous year's Sonic Hacking Contest. Considering how long he's been in the hacking community, he is the best possible candidate to review such creations as he's the expert in this field. Videos of this kind typically last upwards of 10 minutes with 18-21 minute reviews being fairly prominent.
 * Let's Play - usually delegated to livestreams (though not always), RHS picks a game/mod/hack and plays through the entire thing from start to finish. Dependent on the length of the game (or indeed, the length of the stream) this can go on for a while, with the maximum time spent being around 3 hours at most.

How he inspired Matt
Matt claims his review style is a blend of redhotsonic, somecallmejohnny, RadicalSoda and Cybershell. He took the light-hearted tone and the occasional skits of a standard RHS review and redrafted them in a way which suited himself, and these became a key component of Matt Reviews. Much like RHS often does, Matt will update his audience about things regarding the channel, as well as any major thing which may be happening in his life which may affect his upload schedule.

Matt sometimes speaks with RHS about a few things, and has yet to finish a mod which truly puts RHS into Sonic Mania, but that's a story for another day.
