This video compares the graphics between Plants vs Zombies: Battle for Neighborville on PC on Ultra graphics, and the graphics of Plants vs Zombies: Battle for Neighborville Complete Edition on the Nintendo Switch.
Haven't seen it mentioned here (also late, I know) but the water graphics on the Switch version simply SUCK. The Diamond Gnome quest in Town Center where you have to cross bridges in the water is nearly impossible (but still doable) because of how opaque water is in the Switch edition. Also, hi.
The fact this game doesn't run like crap on switch is honestly amazing considering how for the most part the game looks no different between the two versions. Obviously, switch isn't as good visually but it still looks very good.
