Obviously from a gameplay and QoL perspective each expac brings something new to the table so comparing on that part is pointless. So the poll is only to compare th expacs based on the setting, atmosphere, plot, characters, level design etc.
Well i say expacs but I will include an option for the base game as well cause there might be some who prefer the base game for various reasons. Do share the reason for you choosing the respective option.
I will start…my choice is AoM. I’d have gone for the base game only since helping rebuild Homestead and DC while defending from their respective threats is still an absolute favorite of mine. But post-Homestead the focus of the plot shifted from humanity’s survival to a cosmic threat known as the Loghorrean. Not saying I hate it however the base game’s ending is the reason why I can’t pick it as a standalone option. AoM is my favorite because it maintains its focus on huamnirty’s war and by the end of it even reveals that humanity might stand a chance against these otherworldly threats.
Now I am not implying FG was bad, it was an absolute blast to playthrough it. I didn’t mind the shift from the base plot because I knew what to expect having played the Kymon storyline in the base game. Plus since it had a lot of Eldritch Focus it would have been weird to shoehorn humanity’s current struggle into. It shed some much needed light on the inner workings of the cosmic beings and tied up a lot of loose points in the side plots so I loved it. But it is too disjointed from the main plot for me to consider it the best expac.
