I mean I would assume so. I primarily played inquisition and origins on console and never actually played the second. I would assume there's a modding community but don't really know.

Outfits, weapons, junk is worth real money.

I played through the third recently, yes there are a few mods. The game isn't very mod friendly so there's not a ton there but I found like a dozen or so that were worth installing on nexus.

Game still kinda sucks but good enough for one play through if you liked the first (two)
