I remember watching a little bit of cobermani I think along with SMG4. (Still watching SMG4 lol) then I also had a minecraft phase where I watched some PopularMMO's and DanTDM. Then I moved to early ssundee (don't worry I don't watch new ssundee lmfao)
Good Mythical Morning, Markiplier, Jacksepticeye, SkyDoesMinecraft, Deadlox, SSundee, DanTDM, Game Theory, (early) Game Grumps, CaptainSparklez, muyskerm, then got introduced to PBG, Chadtronic, Scot the Woz and a couple of others thru @bradchitis
Cobanermani, lamarr wilson, cnd, redshockinc, alpharad, ninkendo, negas, ded, mayro, fearsome fire, games over easy, etc. Still watch a lot of them, they're all great
Superskarmory, chuggaaconroy, Marilland, smosh (just Anthony and Ian, modern day smash kind of sucks lol). Probably many more i am sure but these mentioned are like the reason for my YouTube addiction to this day.
huh
many
but I'd say that the most stable was... Erenblaze, though I stopped watching him last year, not because he became cringe or some shit, but mostly because I had other things to do and I forgot about him
