Being recognized as the only sane choice by people across the political spectrum and by nonpartisan organizations that rarely if ever endorse presidential candidates is generally going to be helpful for a campaign.
While there are plenty of people on Lemmy acting like this is a deal breaker, I highly doubt any of those people were ever going to vote for Harris.
And even if there is a nonzero number of votes lost to third parties or staying home because of this endorsement, those lost votes are almost certainly less likely to be in battleground states, and are only worth half as much as any independent or republican leaning votes that would otherwise have gone to Trump.
I expect it to be a buggy mess that has lots of potential and doesn’t deliver on half of what it seems like it should do. Then after a year or two it will finally be patched into being mostly stable and mods will have reached a point where it can mostly be turned into the game I actually want. However there will be a few creative decisions that I absolutely hate but which are so unnecessarily locked in that even mods can’t fix them, so I’ll have to just accept them as an irritant that I will do my best to ignore.
