Dragon Age is interesting series of games, where first one was so incredible hit ... so the studio decided to never do anything the same way ever again.
Why you ask? I have no idea, asking the same question for years ... maybe they just dont like money or sucess.
Looking at trailer OP posted ... i had same feeling as many other people, that this was just some skins upcoming for Fortnite ... zero interest, maybe even worse.
Looking at gameplay reveal we got yesterday ... well, its 100% not Fortnite, thats good i gues ... but it felt like hybryd between DA-II. aka, the worse one of series and DA-Inq. aka, the most annoying of series.

I keep saying this for years and will keep to saying it on ... all 3 Dragon Age games were awesome ... Origins, Awakening, and Witch Hunt!
