It plays like the Harvest Moon games (if you've ever played those) where you spend daily life in a town with your own farm, and in time after getting a candidate's affection, you can marry. The twist however, is it's also an RPG. In the main games, you play as a character with amnesia for some unknown reason. Then afterwards you go about daily life doing things and fulfilling requests for the villagers and that's how you go through story progression. The games play pretty fluently, and it's fluency is increased with each new game. As for RF4, the game is really fluent, can be played in 3D, has short 3D anime cutscenes when you meet new characters, you can marry some characters who were once bosses, you can play as a boy or girl from the beginning, you are a prince in the game (for reasons unknown since I have not played the japanese version as I'm waiting for an english release, but what I do know is that the choice was made seven though the main character is a total stranger as he/she was saved by the dragon that's partially in charge of the town & castle after the main character was falling off from an airship and that the character has amnesia) and the system for expanding the town is with a seperate currency than money (which if you think about it, could be a good thing). Also in 4 you can be married, but you can also hold a lover's state with another character, but you can't do so before you're married and that this option is only available in 4 (in the older games and spide games, I think that if you tried to go on a date, you'd be caught and get dumped by both girls, or rather, in the case of RF:ToD/Oceans, both guys.) And also, a friend I know that lives in Japan said that after marriage, the game's difficulty increases. Also, I believe you could get married before the endgame in 4 whereas the older games you had to get married aftergame, at the end of the game, or in RF2's case, at the end of the first half (which is basically all like Harvest Moon. The story only kicks into high gear at the second generation where you play as your child searching for the father, or rather, you after when you entered the second gen.) As for how many saves you can have, in the main handheld games, it was up to 3 save files, while in the two games for the wii (though one of the two also had a PS3 release) you have like around 15 or so. (Though I think it was 99 max for Frontier. Don't remember, but Frontier was a special case since it was localized by XSEED instead of Natsume.)
