Learning from a wiki can be difficult if you're new to programming. That's how I started and I ended up bugging Maurice to no end (well, the fact that I'm not bugging him now means it ended I guess...).
Those videos won't teach you everything, as the series was discontinued, but it gives a great starting place to work from.
listen out if u wanna do this srsly dont do love or dont start with it. ALSO dont start with that shitty drag and drop things like construct 2 and game makers which chromosomes use to make madness games and then realise it's not all that easy in the real world.
just start straight up with a language that actually will be useful big scale like shit like c# and html5 n that (not java fuck java).
actually if ur under 13 go ahead and ignore but if ur over 13 listen to me trust me. cause if ur under 13 u'll just get eased into programming with lua but when ur over 13 no time for that
