1) u dont need to create new account for each region, all u need to do now is change the region in your account under web site (not inside switch). everytime u want to load a game, it will ask you which accounts do u want to load under, i always load under my main account cause all the saved files will be there
2) https://eshop-prices.com/ can check and compare yourself. sometimes argentina/brazil/mexico depending
3) no risk, just that export set, if got anything wrong, need to ship back, unlike local set u can just send for repair in singapore. but mine is export set, no issue
4) yes u can buy kr game and play in eng version on yr switch
Thanks! So meaning to say that you can just log in on the web across various eshops, buy your games and everything will pop up in your Switch?
BTW I read somewhere that you cannot switch eshops if there is remaining credit. Is that true?
