>>522220731. SwSh was their first attempt at an open world and the first mainline game on the Switch. They had an excuse with the new hardware, people were willing to cut them a break.
2. SwSh was not nearly as unstable. Its framerate was mostly decent, while SV chugs like absolute ass. Bugs are another huge issue - SwSh was a mostly bug-free game. While there were issues, they weren't universal, and it was hard to outright break the game. SV is much worse - the camera going through the map every time you battle against a cliff, weird animation bugs, and all kinds of other Bethesda tier shit.
3. SwSh's waifu game was on point.
