What's good about it? For me, pretty much everything.
Graphics - Amazing, HDR 4K is so rare on a PC game, love it!
Combat - Fun and Fast, best in series: easy.
Dialogue - Natural feeling and more organic than previous ME games.
Story - Slow burn, but starts to heat up at the 10 hour gate, it's very good so far.
Characters - Likable and unique: Liam is the bro, Cora is definitely bae.
World Building - Mysterious and grand, there are many layers here.
Voice Work - Mostly great, the odd oddball though:
is amazing.
Music -
Phenomenal, maybe my favourite equal with ME1 in this department.
Sound design - awesome: ambient chatter and such is just right.
Lore - Loads of it, lots of cool tie ins with the ME:T too.
In my 10 hours, I never once thought "that's some horrendous animation" either, it's all blown out of proportion, meme riots incited beyond reality.
The game honestly feels like it could be a 100 hour epic at this rate, so much mystery too....no I'll be jonesing out for a week: god damn it! haha.
