I could swear I warned you some years ago this would take a long time to create from scratch (you have the artistic muscle but not the programming muscle) but I can't find that post now. Perhaps over the years I've warned so many projects that make this same "mistake" - it happens over and over again - that I am mistaken and never actually said it here, although even if I had I'm sure it would have fallen on deaf ears since you understandably have a lot of self belief.
Yes, I think I do remember you talking about that - and the response you got (which remains just as valid today) is that we don't much appreciate it when people go around Vega-spamming.
First up, it's just plain stupid. A guy is making a film, and you're telling him he'd have made more progress had he made the film as a book... huh?
Second, Vega Strike has a long and ugly history of having fanatical idiot fans, who go around telling the rest of the world to switch to their engine, and we've had enough of that a long time ago. You have neither the right, nor even the basic knowledge needed to assess what would be better for the Pioneer team. It's just plain insulting that you would come here, and arrogantly assume you know so much about their project that you can tell them what's better for them -
don't do it.
