If I buy the full version, will I get future updates without having to pay again, or would I have to purchase the game again?
Hi! No, buying the game goes through Patreon and this is a subscription service. When you purchase Game Waifu and immediately cancel, you'll get access to all waifus thus far. If new waifus roll out before the subscription expires, you'll be able to get those too. But any waifus that release after that period aren't obtainable unless you renew
