I have played most Pokemon games, but I am deciding between Pokemon Sun/Moon/Ultra and Brilliant Diamond.
I have never played either of these games not even their original versions. What do you think?
Additionally, is Sun/Moon good or is the Ultra version better?
I've played both Diamond and Brilliant Diamond. To be honest, I don't get where the hate is coming from for BD. It's got a ton of quality-of-life changes compared to Diamond. If you had the choice between the two, I would certainly recommend BD, especially if you're used to the the QoL from the newer Pokemon games. Whether or not BD is worth the money is a separate question entirely… but at least that can be solved by consulting some online "vendors," if you catch my drift
As for S/M and US/UM, what I've heard is that S/M has a more coherent story. US/UM apparently chose to abandon the story near the end and shoehorn in an incoherent ending, with the intention of using the new ending to build up a stronger post-story game. The choice boils down to whether you care about the story more or whether you care about the post-game content more
Well either way I’ll play on the steam deck, so not needing to switch between screens in a plus for brilliant diamonds.
In regards to s/m and us/um. What if I just want to beat the elite four which would you recommend? I’m not sure I care about the store or the post game content. I’m not even sure what post game content is, so maybe I’d care, but probably not.
