I'm mostly excited because of lack of character class to be tied to. If possible, I plan to make an offensive tech powers/firearms hybrid build. Something like Sentinel, minus the biotics maybe. The whole scanning and collecting new technologies to make upgrades and new weapons also seems to be very tasty as I tend to explore every square inch in such games.
But what made me a little worried though...
-Due to complications in the awakening process, your sibling won't join you in combat but you can interact with them and build a relationship
The last word to be precise. When translated to Polish, it's meaning in that context can vary from simple interaction to even incest O___o. While I've got absolutely nothing against the variety of romance options and orientations in BioWare games, that would be too much... So I hope that I may have only misunderstood that part or it's just my inner paranoia xD.
Anyway, I'm very excited to see the whole family in action
