If you've ever thought about grabbing Overwatch on PC, then you might want to take a look at the sale on the Korean and Taiwanese Battle.net stores.
Usually it's not recommended to buy games in other territories, due to region locking, languages and other shenanigans. But fortunately for Overwatch, the game is completely region-free and available in English, irrespective of which Battle.net store you buy from.
The deals are pretty similar: you either pay &won;22,500 through the Korean store (~$25.50) or $NT650 (~$27.50) through Taiwan. Either deal is a massive saving on the $69.95 for the base version of Overwatch through the US store, so if you've been holding out or you want another account now is a good time to jump in.
If you are firing up the game for the first time, you'll want to refer back to Nathan's guide to get you started. (And since new players often gravitate towards Bastion, you might like to know what changes Blizzard has in store for the bird-loving robot turret.)
