I've been playing Advance Wars 2 on Switch.  There are some difficulty spikes where you've got these 'boss missions' where you need to take out a big factory.  The rest of the missions are pretty easy, where you're clearly being set up for succes.  The models for the different commanders are generally great too, where I'm trying to make out if it's animated 2D art, or high quality 3D models.  Some seem to be the former, while some show tells of the latter in how they're animated.  As for the limited voice acting, it's like they have 3 actors tops do all the voices, which does come off as pretty cheap.  I'm playing the localized version, since you still can't set langauge settings per account, only per system, so perhaps the situation is different in the English dub.
