I've been watching this on the background while working on art, here's a few highlights from 1 hour and 20 minutes in:
>guy says Wurmple evolves randomly even though it evolves during time of day
>guy says Fairy type was a good addition because Steel types were weak (lol)
>guy says contests were a waste of devtime
Just to name a few, outside of that he's making really good points like how unbalanced the game is in general, how EXP share literally trivializes any challenege in the game and removes any semblance of exp management, how heavy handed the tutorials are and how Pokemon itself fails to capitalize on it's good features (DexNav) because Gamefreak is retarded and treats every new addition as expendable.
Bretty gud so far, it should be noted that this is closer to a commentated runthrough of the game as he nitpicks every individual area and how they affect the player overall rather than just a flat review.
I'd love to see this guy thrash (Ultra) Sun and Moon since going off of what he's saying about ORAS, he'd likely hate USUM.
I'll keep watching and summarize any other things he says and make a tl'dr version at the end if this thread is still up.
