Most playthroughs are basically review-whilst-gameplay-shown situations, whilst hellfirecomms definitely has that element, what attracts me to hellfirecomms is the witty snarks directed at the commentators, the games being played and the characters, occasionally a comment is thrown at the fanbase of said game and their tendancies
The first one I watched was Sonic The Hedgehog 2006, and never has hearing a couple of hours worth of people complaining
been quite so entertaining (and it isn't baseless bashing either, it's genuine and grounded argument in disfavour of the game,however in often in a piss-taking tone, and credit is
given where it is due), since then I have watched all Sonic playthroughs and many livestreams.
The livestreams offer more variety, you may the more professional review-while-play/pre-recordedgameplay type deal to be uploaded on youtube, a semi-professional reveiw-and-chat-whilst play, or complete and utter silliness, which may or may not possibly involve one of the commentators saying dirty things in an extremely convincing impression of Mickey Mouse.
