Yeah i agree, our trailers are basic, juste in game capture with music.
No one in our team was able to put a voice with tremendous English accent
I can’t agree more with you. Knowledge about game dev / graphics / network or steamwork is very precious and matter more than some dollars for now… (humm depends how many dollars to be honest :p)
I want to say also that the trailer is, as you pointed, good to show what could be done with JME but all dev must be aware that JME can do A LOT BETTER.
The only true limits are your skill, time and money
