Fantastic to hear! My favorite way to play the LEGO games is portably, but they've have been a little hit and miss on the Switch.
The newest one I tried was LEGO Marvel Superheroes 2, and it ran pretty poorly. Low resolution and a pretty bad framerate.
LEGO City Undercover was OK, but also had framerate issues in the open world, but was more forgivable since it was pretty close to the Switch's launch.
The port of the Harry Potter collection was really good though. Movies 1-4 had a great framerate, and the other game seemed good too.
This upcoming one is actually a complete grounds-up remake of The Complete Saga + the New Trilogy. They've talked about a completely rebalanced combat akin to Souls games (light attack/heavy attack combos), revamped mechanics, new hub world where you can visit all in-game planets like No Man's Sky, new visuals/camera etc.
Wow, I hadn't heard about all of those changes, only the open world stuff I'd read about.
One thing I love about the LEGO Star Wars games is that they tend to use them as leaps forward for the series or at least try new stuff.
Star Wars 3 (the clone wars one) was the first one that took advantage of the 360/PS3 gen and it looked great, had lots of units on screen, large scale set-pieces, and even introduced an interesting RTS mode in some of the levels.
That mode ended up being too easy to be really interesting, but it was still a cool new thing.
