I have been playing ultra sun for the last few days and am about to finish ula ula island.
It was kind of entertaining at first and I enjoyed the amount of decent mons you could get early on but the story is kind of boring.
Team Skull is also completely retarded, how can you go so wrong with the bad guys? They go yo yo wuzup my nigga and do their little dance every damn time and it's just fucking retarded.
There's also that rotom-dex and it's annoying almost to an unbarable degree.
What I can give it is for a 3d game it has better scenery than swsh and sv.
The pokemon uber app is pretty neat.
The towns seem pretty nice and I like the island theme but all the bad definately out weighs the good.

I'll probably push through and finish the game today but this isn't a game I would replay ever again.

I'm also not using the cringy dance z crystals.
