The base game for me at least is ¥9,790 (£45.90 / 52,90€) (the prices of this differs depending on where you live in the world), and also CT is included in the price (which is 10%). That’s NOT the case for US gamers as you are NOT paying $69.99 as SALES TAX exists meaning you’re paying more than that, I wouldn’t be surprised if the same thing defaults at £69.99 & 79,99€ just for the base version.
Game isn’t out yet, so how do we judge if the game is worth the price? Also never pre-order any game, especially if its digital. Why not wait until launch? Then you can watch reviews or read opinions and then decide if the game might be worth it? Also on Steam you can play the game up to 2 hours and have a time frame of 2 weeks to refund, if you don’t like the game (just don’t refund too often like that, as they don’t want you to abuse the service).
