You See Yourself Playing for the Next Year or Longer
If you already love Battlefield 1 and you can see yourself playing it for the next year or so, think about committing to the Premium Pass.
If you're currently logging onto Battlefield 1's servers for several hours each day/night, don't think twice about picking up the Premium Pass. You'll almost certainly get your money's worth by the time everything is said and done.
Battlefield 1's replayability is solid but the Premium Pass and its accompanying DLC will only serve to strengthen it with new content and experiences.
If you're already hooked on the game and its various modes (we're still hooked on Operations months after release), Battlefield 1's Premium Pass should be a no-brainer.
Keep in mind, we probably won't see many deals on the standalone Battlefield 1 DLC add-ons (they cost $15 on their own) so the Premium Pass will ultimately be a deal, shaving $10 off what you'd pay for all four DLC expansions on their own.
