Welcome to CivFanatics!
I highly recommend Yoruus' channel. In fact I've registered here after lurking for years just to suggest his videos... The dulcit tones, his occasionally brilliantly broken english (he is Polish)
Moriarte and Maddjinn are my two favorite. Elcee too is interesting.
I'd just wish Moriarte would speak louder (sound quality is overall meh).
When I started the journey to push Diety over, I started with MDj and went back and watched most of his stuff. Can't think of anyone who has contributed more to this community than he has. Which is why I find it sad when people who might be better players, think it's cool to libel him on his own threads. Pretty sad, but I digress.
MDj shows the ropes and also has nice insight into how the game was developed. It's also amusing (if not baffling) to see how he just seems to waltz through diety game after diety game, maybe not with the tightest gameplay, leaving quite a bit of room for error, and never breaks a sweat and ALWAYS comes out the winner. Baffling in that if I make even one mistake I usually end up paying for it on the rear end.
Then I moved to LC for the adult version of how to slap the AI in the face. Not 20 turns of preparation, but an uppercut to the face of a pre T50 triple DoW, making the AI wish they never looked in his general direction. The most entertaining must be he last one where the only way to stop Korea from building the last spaceship part was to nuke the absolute P!$$ out of him, bomb after bomb and eradicate their every last crap city he spammed on one tile islands across the map. Boo-yah.
But now I've grown up a bit and have to say calling my favourite which Moriarte's LPs. Advanced play, lots of explained foresight 20-50 turns in advance with nice smooth subtly witty commentary.
Anyway this thread has turned into a bit of a fanboy party. Good luck, OP, with your training.
Can I just confirm I'm right in thinking MP = Multiplayer?
