I've played BioWare Games from the beginning, and they have their ups (Dragon Age: Origins, ME 1,2) and their downs (Dragon Age 2, and for some, Inquisition). This one is definitely an "up". Much larger in scope than 1 or 2, you may not "land" on as many planets, but the ones you do are different and meaningful. Unlike Inquisition, the side quests actually mean something and have an effect. You don't have to craft, but you can make some nice gear. You don't have to gather resources, but if you want to craft they're easily purchasable. The visuals are beautiful. I'm about 50-60 hours in, and I've only encountered a few (3-4) very minor bugs. The initial load when starting the game is long, but I haven't had long load screens at any other time, including fast travel.
As a negative, the menus are a bit of a mess. In crafting, there is no way to sort your blueprints, so finding the one you want is a pain. Tracking all the quests in a game with a TON of them can be a pain, but at least we CAN track them, and see what stage they're in (unlike ME 3).
The visuals are Mass Effect. Everything looks like it belongs in a a ME game. Only 2 "intelligent" races, but this game only covers one cluster in the Andromeda galaxy. It stands to reason that more are "out there" for future games. Yes, some faces are... odd, but that's been every BioWare game ever, and isn't that noticeable when you're into the game. I find the story interesting, and it doesn't make feel forced to rush through. ME3's story had me feeling like I was trying to "beat the clock", and ME2 forced you into missions based on how many side missions you had done. Andromeda allows you time, like you're truly there to explore. Combat is an improved form of ME3/ME3 multiplayer. The jump jet increases mobility and allows you get around the battlefield quickly. Weapons all feel different. Smart cover actually works, and works perfectly.
Mulitplayer is exactly the same as ME3, with the sole exception of the jump jet, which makes it a lot better. Sessions give you more than enough "credits" to buy upgrade and supply packs every 2-3 matches. Matches start quickly, and I haven't experiences any lag, but I'm usually the host and I have very strong internet. Of note, all of the above was on my Xbox One S, which is my primary console. I've only played 3 hours on my original Xbox One, and the graphics were slightly fuzzier there.
All in all, I love the game, and I think a lot of people are dog piling and being hypercritical. To me, this game is almost on par with ME2, better than ME3, and way better than Dragon Age: Inquisition.
