If you got your money's worth out of 2142 then you'll be fine with BF6, it's better than that. Beta was enough to know 2142 was awful
The maps are pretty bad imo. Atleast the maps featured in the beta. Think more link COD with vehicles
The release does feature larger maps but they do still seem to be smaller than the “all out warfare“ sized maps of previous BF games.
It seems the devs doubled down the the community's complaints about the maps being too big in 2142 and decided to go much small with BF6. When if they were competent BF devs theyd had realised that the issue was the maps were just bad in 2142 and not necessarily too big but too baren and sterile.
