Hey!, I'd Love to help but im restricted cause i dont have a capture card. I can however make art! I'm willing to make a quick screen play just to get the jest of it. what we do need to organize though is what we want incorporated! heres my suggestions
Building: this is like 40% of the game so duh we need this
digging: again this is a large portion of the game
crafting: another big part of the game so we need to showcase it and it's expansiveness, we can do that through crafting a few cool items and scrolling through the quick craft list.
Skill system: I know this is a big positive to the game, ive gotten people to play it just for the stats! not including this in the trailer would be a crime! this can be simply and quickly put in, just show some scrolling through the skills so people can see all there is to offer.
Combat: obviously we need to include combat, both pvp and pve to show off all capabilities!
Exploration: definately need to show some exploring, whether it be the oasis, underworld, big caves, whatever it is make it grand and look badass!
Potential: we need to show off some of those big builds and awesome stuff so that people can see that you can make some awesome stuff in the game. most importantly INSPIRE PEOPLE.
Also side note: when building try to build with more unique pieces so people know there's more than just cubes. and as for digging try to get some cave in footage and spider dens.
