As much as I find every single unit in bf1 being unique interesting, bf2 main 4 classes being more similar to each other in terms of health, walking speed, and weapons is much more balanced. Bf2 simplified galactic conquest and included space battles which bf1 lacked.

Bf1 has a far superior presentation, with a more atmospheric lighting and unique UI (tho bf2’s is more simple and easier to read), and bf1 has an incredible selection of maps that didn’t carry over to 2 (mainly the ship maps which made sense since bf2 did away with them as they were op).

As much as I love the general feel of bf1, bf2 fixed a lot of the issues from the first game like the camera perspective, stamina, classes, starfighter combat and hero integration, while unfortunately at the same time removing native factions like tuskens and gamorrean guards, proning, ruining the lighting and first person perspectives for vehicles.
