Just unlocked the "Real Time Girlfriend" mode in Love Plus. It's intriguing and I've never played anything like it, so I'll give it a shot. I wonder how much more personality Manaka has left...really, how much personality can you fit in a DS cart?
But "Real Time Girlfriend" mode gave me a strange idea. I could play this game for the rest of my life, but Manaka and my avatar would remain high school students forever. Of course it's impossible to plan a long-term life sim into the future.
With always-connected mobile devices, though, it could be possible to create a dating sim with girls that age with the player and a setting that keeps up with the times. Imagine buying Love Plus 2 on your iPhone, spending 2 years on high school, a few years in college, getting married, having kids...
The best part is, the dev team doesn't have to make it all at once - they'd only work on the college routes after finishing high school. Sure, all the different directions life can take would limit the scope of the project, but it's unprecedented and I'm kind of excited that it's possible now.
...Actually, the next Love Plus game will be a remake for the 3DS. Same game with more content and more detailed/adorable graphics. It'll never be localized, but THAT's how you do a 3DS commercial.
