First off, Mark has plugged. He spent a week at sdcc booth signing GS#1 which he wasn't paid for. He has plugged Magika and it shot to top of Hulu.
But beyond that, REDG hasn't had anything for him to plug (yet). He can't plug stock. That's illegal. But you can bet yer butt he will plug again when powfolio launches and when his comic comes out. So your whole argument is silly.
Magika was first announced in 2013. It didn't hit until end of 2014. Shockwave was announced in 2012 and didn't come until 2016. These things aren't fast.
And don't think this is only REDG. Marvel movies (Disney) are set up to 7 years in advance! You can't say it is bad budget or management. Entertainment businesses don't move at the speed of light. Publishing a comic takes like six months start to finish.
REDG isn't a company measured in can't, it is measured in Yet. That's how I look at it. It is what I believe.
You can believe as you like but evidence is all looking damn good. I use comics apps. This looks amazing and it isn't even full beta yet.
