In one part , if some people reach the commercial state,
for 99$ and some more money, perhaps the overall money invested really worth it ?

Yes for people having baught it 99$, they should not pay more.
Really they should not charge people having put their money and confidence on the engine and that allowed to Torque 3D to continue to survive !!

Or they should have been clear from beginning saying :
- Next Upgrade you will have to pay some amount !
Perhaps they have done good sales and changed strategy, thinking we have enought people now ?

They seem to have hired a good bunch of people, i am curious about how they will pay them a salary ?
I'm not sure their character packs, or vehicle pack, ro even engine update will suffice ??

Perhaps they make games behind the scene ?

Well like i said, i tested it well , i didn't like the lightening at all, and the visual annoying bugs here and here etc ... so not for me i have what i really need : A8 and some two others 3D engines

I just found that marketing point , just sad, because it has been a surprise, no one knew that ....
