I’ve played Battlefield 6 since launch. I’m excited about it, but also a bit disappointed in places. Here’s how it broke down for me:

Battlefield 6 goes whole hog to bring back large scale battles, destructible maps, and enough players in a round. It does a good-enough job with nice-looking graphics, good sound, and gameplay that plays like classic BF. But some of it has the flavor of being unfinished or buggy. Overall, it's more like a version of Battlefield stepping back onto its feet rather than leaping forward.
The campaign is effective. It is a build-up to get into multiplayer. The story is too familiar: soldier fights private military enemies, missions take you through cities like New York, the graphics are beautiful in cutscenes.

Problems hit quickly. Enemies' AI and your friends occasionally do stupid things. Hit registratiton works the same as multiplayer, which is weird for single player, right?
Campaign doesn't impress. It's built on hackneyed cliches, expected story beats, and the occasional jolt of tension. But it never takes you anywhere. If you only care about shooter missions to complete, it's fine. If you want emotional depth or narrative panache, you'll be disappointed.
That's where multiplayer shines. Conquest, Breakthrough, and new maps are enjoyable. Matches are big enough, map designs are good, destruction mostly gratifying. It feels like Battlefield again.

Portal mode is unique. Custom maps, rule modifications, scripting for AI, custom UI, blending maps from other Battlefields. Portal persistent servers have community servers permanently available in browser.
Issues: hit registration work bad in most games. You shoot somebody up close, see effects, but no damage. Devs have recognized the bug and I hope working on deploying fixes. Crossplay probably make it worse.
Loadout progression is confusing. Once you've unlocked what you like, you don't want to let it go. But initial guns are weak, attachments are locked firmly after kills and assists, which are pointless. And launch content is scarce: not enough maps, vehicles, variety. Portal compensates through enabling players to build, but just for the people who have fun in custom modes.
I’d give Battlefield 6 82/100. It delivers fun, especially in multiplayer. Campaign is okay but not great. Bugs and design gaps hurt the experience. Still, it’s promising.
