Even though I do also play it with friends, I feel like they are great for feeling included even when playing alone. Since teams are split into 4 or 5 player squads, if you get a squad that sticks together it is a wonderful experience, having strangers watching your back and charging into action with them. You work a lot outside of your squad too, as there’s 4 distinct classes which all provide something important to the team
These days they’re super cheap on sale too! The last couple weren’t as good as the ones before, but if you haven’t played a game before you might still enjoy them. Though my favourite is Battlefield 1, which still has active servers despite being 8+ years old.
