I... Do
not vibe with the mindset of "Just Port Ultimate!" That's just gonna get super stale very quickly. We
have Ultimate already, everyone and their mom has Ultimate, we can always go back to it, especially if Nintendo's smart enough to give the Switch 2 backwards compatibility. I feel like in some cases it's an extension of "Hype Syndrome," where people get more fixated on the hot new fighter and how big we can pump up the roster instead of the actual gameplay.
Plus, there's a crapload of gripes people have with Ultimate that can't be fixed by just making the same game again but with more fighters. A simple updated port won't update criticized movesets like Ganondorf or Sonic. A port won't fix the bloat of grassy 1-1 stages, retro stages, and traveling stages. An updated port means we keep all eight Fire Emblem characters, and all the debates that come with them. If we actually
got an Ult DX, I feel like a lot of people asking for the port might change their tune when they're reminded of all the little issues that would be preserved
I think there’s a good middle ground to aim for here. I think you ideally want to aim for the source material at least on a visual level. If the mechanics of the source game are too complex, I think it’s totally fine to simplify them so they gel with other Smash characters. I feel like different kinds of movesets appeal to different people so I wouldn’t say any approach is inherently bad unless it’s universally disliked.
A little late but this is how I feel. If you're a fan of a series, you'd expect things to more-or-less like it is in the source material. If it deviates too far from that, it's gonna feel weird. That said, it's also fun to see Smash freestyle with movesets a bit, give it's own spin on things. And obviously, "Two Flickies Down Smash"-type movesets feel super sterile and forced. Thankfully Smash doesn't really do that like some fan movesets do, but you get the point - References are fun, but that shouldn't be
all the moveset is.
