Your question is phrased wrong. There are no 'love' Sims games. http://en.wikipedia.org/wiki/List_of_The_Sims_games The above link is a list of Sims titles. Rom U offers the English and Japanese versions of all the Sims Gameboy Advance games.
Well,if you're interested in fighting as well,there's Riviera:the promised land-it's a boy pursues girl game,it's pretty awesome.Then there are the Summon Night Series,but it doesn't have much of a romantic atmosphere.There's tales of phantasia,I've got it,but I've never really gotten around playing it,it's also a boy pursues girl(I'm a girl,so you can tell why I'm not so interested).Well,that's all I've got now,I'll see if I'll get more(that is if anyone sees this post)
