*Saves and/or downloads all the links, while squealiing* Thanks
(This is why USHI is Psychic! I just began actively hunting for dating sims yesterday and was going to make a post, but viola, someone all ready did!)
But here are some games I know:
Another game with dating sim aspects is "Avalon Code". It's an save the world RPG but you can date several characters and who you choose can affect the plot (somewhat.) It's by marvelous and translated by XSeed, I believe, and out for DS. (It's a really great game, to be blunt; I really, really reccomend it.)
Otherwise I'd recommend Princess Debut as well, and there is another game by them, called Kurukuru Princess (I don't know if it has the dating aspects; the translated version in us is Imagine Figure Skating, but tbh, the translation is horrible and has so many errors...)
The Princess Maker series isn't purely a dating sim, but it does have a DS version of Princess Maker 4 (it's Japanese only sorry) and your daughter you raise can end up with several guys (or girls, in the DS version I believe? Or that might be PC version only... but I'm pretty sure it's on the DS one as well...). (For Computer, there is an abandonware English translation floating around of Princess Maker 2. It's not the "refined" version so the graphics aren't as good, but still excellent and the translation is very good.)
For computer dating sims I'd try...
Another website that has a lot of dating sims is Hanako Games. You really have to go through and pick what you want from it (some I find are very sub-par) but some are great. http://www.hanakogames.com/index.shtml
You could also try Nummyz.com if you're not picky about art. http://nummyz.com/games.html
There is a series called Touhou, apparently there are fan English translations floating around, but I can't find them. Anyway it's not only dating sims, I think it's actually some sort of space-shooter game? But it has dating sim listed as a sub category and I know they are very, very popular in Japan.
Another game in English for computer is Yo-Jin-Bo, apparently very well liked and datingsim/visuel novel ish.
P.S. I'd love to hear of more dating sim games... COmputer, PSP, DS, guys, girls, whatever...
I'm going nuts waiting until I can finally buy Yo-Jin-Bo.
Or any Japanese ones that aren't too difficult to read? (buyable is fine too.) Maybe a bit under newspaper level...?
I'm so practicing Japanese with the ones you guys listed though.
