I meant to say Z-A. My bad. Arceus didn’t really hold my attention, likely for the reason you mention.

It definitely depends on how much they incorporate improvements from Legends: Arceus Z-A (one of the side games). Gens 6 - 8 were all so easy that a popular way to play each of those is with a difficulty mod, if you are able.

Gen 9 tried to mix it up a bit, but as another user mentioned the performance on the Switch was so poor that it was hard to enjoy.

Legends: Arceus Z-A has introduced several quality of life features that could be game changing if they make it into Winds & Waves, but we shall see. This could be the most fun mainline gen, if they do it right, or they could fumble it again.

Edit: Looking back, both times I meant to say Z-A I said Arceus. Whoops.
