I...really like this version of Go Aestivalis. It's so relaxing.
They did an exceptional job with the arrangements. Only ones I don't like are the Unicorn bgms. You would think they paid more attention to the list they made for the Premium version, but no, the ones in the standard edition are as good as the additional ones.
The intermission bgms are really, really good too. I have changed only a couple of them and put tracks from Xenoblade and Interstellar, but only to substitute old rearrangements from previous SRWs. All of the new ones I absolutely dig.
What really got me though are the sound effects. The sound when mechs transform is really explosive and loud, while the change of phases is underlined with this sort of laser-weapon-like effect that makes it really stand out.
As someone who's new to SRW, which game mode should I play? Will "Standard Mode" be too intimidating for beginner?
To add to what Shouta said, I would suggest to also play the Guidance Scenario.
Ignoring translation quality, how is Moon Dwellers? Barring the inclusion of a number of specific series, I actually like the OG cast more than most of the regular games (The Z2 PSP games are the only mainline installments I've made it through, but they were great.).
Challenging gameplay-wise but boring plot-wise. I really don't like the direction they took with the characters. Outside of the way they look they just feel so similar to each other. One thing that was great about the first OG game was the recurrence of themes like the Huckbein being this sort "haunted" mech, Ruysei happy-go-lucky attitude through all of it, the story behind the School children all living in awe of Ouka, and the Shadow Mirrors being the good guys becoming the necessary evil.
In 2nd OG and Moon Dwellers they just kept adding characters and they just... can't work out a way to make them interact with each other outside of exchanging information, recapping split routes, and introducing to each other. There isn't much cross-over dialogue between teams, the plot is too serious and complicated for its own good, and the only characters that become somewhat interesting are Touya and Galvina.
And the humour feels always out of place, as if it had been mathematically shoe-horned under god knows what pacing standard, ending up completely flat even when it works. A lot of times I'm reading jokes and I think "I should be laughing right now, why I'm not laughing?".
In Generations anything, ANYTHING, Tusk said would immediately crack me up. And don't get me started on how BORING Touma and Sanger have become. Soooo stiff.
Besides THAT the animations are great, the twin system is better than ever and the loading times are almost down to zero. The Bgm list is more of the same, and while everything got unlocked from the start, they really need to get the guy behind V's original bgms to come up with a new soundtrack for OG. Because after 15 years even the awesomeness of Vanishing Trooper looses its kick.
