Yeah, I've got all of the DLC for the game.I am the same. I started replaying it like a month or 2 ago, right now its on the back burner because of Elden Ring. Although I am playing on commander. Did you get the chosen dlc?
I do enjoy the wealth of extra content that WotC provides, but to be honest, it is pretty much a necessity for most of the game's mods.
And the mods for this game are excellent! As a massive Halo nut, I've spent many an hour making my soldiers look like Spartans or ODSTs from that game, but right now, I have mostly just gone for a mostly vanilla experience, but with a couple of extra tiers of weapons ported over from the Long War mod, and some extra customisation options.
