Collectors get out your wallets because there are three Love Plus + DSi XL bundles: Manaka Deluxe, Nene Deluxe, and Rinko Deluxe. Each one is name after the girls in Konami’s girlfriend sim. Pricing has not been announced.
Love Plus + isn’t a sequel, it’s an expanded version of Love Plus. The Famitsu article says Love Plus + has more events such as mini-vacations and more ways to interact with the girls in Love Plus mode.
