Ah okay, that's good to know. I wonder if I'll have to buy Mewtwo since I got him for having both versions initially?You shouldn't have to rebuy the DLC, you'll just have to redownload it from the eshop if that data ends up getting deleted with everything else. That stuff should show up with your previous purchases.
I personally think it would be worth it, unlocking the characters and stages again shouldn't take too long. Getting the customs again will likely be the biggest issue, but for the time being you can just focus on Duck Hunt's since we use one of the custom up specials for him.
However, the lack of people to play this with is definitely a big barrier. It'd be a lot easier to recommend this if online special smash was still there, but it ain't. :/
Yeah, unlocking characters and stages is easy and customs just takes two weeks of Ganon punching bombs on autopilot. I guess I should look further into this project to see what customs are generally used. You mentioned Duck Hunt and I'm pretty sure Megaman uses a different one too?
As for people, I conveniently have a cousin who ditched Sm4sh for a few months in favor of Melee and P:M. He came back to Sm4sh when Cloud came out but I'm sure he'd enjoy the faster, less safe gameplay of SLHG.
