I just finished unlocking every character, and I know it's not news but man what a roster.
I really, really like World of Light. I get why so many people call it a grind, but as someone who has always only played Smash by himself trying to do most of anything in the games has always seemed a bit grindy, so the presentation of this one is more than enough for me. I opened the way to the true final boss and then went to clear out as much as I could--there are still a handful of tough Spirits left, but I think I'm going to go for the ending and come back for those later.
Speaking of Spirits, while trophies might've been a bit more fun to look at, the fact that Spirits do something automatically makes them better as far as I'm concerned. More than that, each one being tied to a specific battle and so many appearing in World of Light makes them feel far less random, which has always been a complaint of mine. (I still don't have the Star Force Mega Man trophy in Smash 4.) I have a little over 700 Spirits right now, including all the Spirits from Mega Man spin-offs: they have at least one from each, 16 total across six series, and that makes me happier than it probably should. ZX is finally represented! Granted, the Model ZX Spirit isn't phenomenal, but it's pretty good for when you get it in WoL so that's something. It's crazy to think I'm not even halfway towards getting a complete collection!
I've been pretty much exclusively playing Spirits mode thus far, but now that I've got everyone I want to try to take them all through Classic Mode next. Maybe I'll find a fighter who clicks somewhere along the way--I've been using Zero Suit Samus mostly, though the past few days I've been trying to get the hang of Greninja. I mean, I'm not especially good with either of them, but...eh.
And I'm still really, really excited for Pirahna Plant. Really excited.
