He say some things we already know thanks to others leaks like:
-Combat is GOW and Witcher 3 inspired according to him(GOW inspired was already confirmed by other leaks)
He also says:
-Game looks great graphically("If it released today it would be the best looking 3rd person rpg on the market.")
-The facial animations are good and not like andromeda
-Says the questing structurs is typical Dragon Age just with a more action approach in combat encounters
-Say can't talk of the story or writing since he only played snippets of missions mid story so he lacked context
-Says you have 3 others campanions you can bring with you(so not only 2 others like Mass Effect like some were speculating after original leak)
-Says that he saw no companions tactics that could be set by the player(personally a little bummed about this)
-You can pause combat(don't know if by this he means that you can pause to give orders to companions)
-Game is 90% finished(though the player character is still missing a voice)
-There is a codex like previous Dragon Age games
-Dialogue wheel does indicate tone of answers(Like if a line you can select it's a romance line it will have an heart next to it)
-Armor and clothing looked good
-On difficulty he says "It's probably what you make of it honestly. I wouldn't say it was particularly hard or easy, and there's probably a difficulty option that I couldnt access.
If I played on normal, then its definitely not dark souls level of hard. Not even close. But I did die a couple times when there were several enemies, so it's not face roll easy. Although I will mention I didnt get to play the tutorial, so that might've just been me getting used to the controls."
-No stamina system like Dark Souls, you can parry how much you want but can't spam abilities
-He liked the game from what he played(3 hours)
