I do think DLC would be easier for me, mainly because I don't know how to go about transferring saves to a separate gameLust academy has two seasons, each being it's own game (each with separate dlcs), while being a dik is a single game, with second season being a dlc. Those are the only ones I follow, tho.
Edit: if I had to choose, I think I'd choose it as dlc, to keep everything (info, engagement via the community, etc) in one page. But every person will give a different opinion on that, lmao.
