If you liked the Shuffle! anime, the Anime-Planet community thinks you'd like:
One day, after a visit to his parents' grave, Teppei Arima spies a damsel in distress, and nobly saves her from a gang of thugs. Relieved and grateful, she introduces herself as Princess Charlotte Hazelrink. Thinking nothing more of this, Teppei soon receives a surprise call from his grandfather, informing him that he is the heir to the Arima business empire and therefore one of the richest men on the planet! Teppei is introduced to his personal maid, Yuu, and various blue-bloods, among them his arranged fiancee, Sylvia - a fencer with a tongue as sharp as her blade. At school the next day, Teppei meets more new faces, including the snooty Seika Houjouin, and - much to his surprise - Princess Charlotte Hazelrink. Still awkward and uncouth, Teppei must somehow adjust to high society. With girls pursuing him at every turn, however, that may be the least of his concerns...
Well, there shouldn't be much further explanation required. Both Princess Lover! and Shuffle! are largely set in a school, both are about a guy pursued by several nubile young ladies and both promise a heaping helping of ecchi humour. Although Shuffle! featured nudity and a storyline, while Princess Lover!'s story is mostly absent and it doesn't yet appear as though anyone's going to get their tits out, they're still similar enough to pair up like this. Also, both titles end with an exclamation mark.
Both titles have male main characters who could more or less have his choice of several different women. A classic theme behind a harem as to which both of these are. Both animes feature compeling storylines that is used throughtout most of the episodes for some fun and enjoyment and to simply build on the characters and the relationships between the main character and the other women. Also towards the end of each series they add just enough drama that will make you want to see it through to the end.
All is not as it seems on the part civilian, part military Aries space station. While visiting tourists or a fresh batch of cadets are just business as usual, a terrorist group planning an attack and a mysterious woman constantly getting "lost" in forbidden areas of the station is not. Soon enough, the regular life on the station comes to a sudden stop as different factions face off in its narrow hallways. And as the battle rages, the masks people wear are torn down. Unexpected alliances and bitter betrayals, love and sacrifice; nothing brings out people's true nature like war.
If you are looking for an anime with about as much fanservice, drama and minor action as Shuffle, then Soul Link is good for you. Inversely, Shuffle would be just as good for the same reasons. Plus, they're both based off of a game.
Keiichi Morisato is just your average college student until one day, fate interjects as he makes a call for take-out food. Unknown to him, he reaches the Goddess Help Line, and contacts a goddess named Belldandy, who grants him a wish. Thinking it to be a joke, Keiichi wishes for her to be his girlfriend 'forever'.
If you enjoy a mixture of romance, comedy, magic and mythology (mainly Norse), then these series fit well together. Shuffle is definitely more harem-y and ecchi and a bit more serious in terms of many of the themes explored, though.
Morisato Keiichi has always had bad luck. No matter what he does or how he acts, nothing seems to go his way. His bike frequently breaks down, his classmates take advantage of him, women ignore and scorn him, and on top of all that, he’s only 5'3". In Heaven, when someone’s bad luck and good luck are so heavily out of balance, Belldandy (Goddess First Class, Second Category, Unlimited) of the Goddess Assistance Agency comes to the rescue. Belldandy grants Keiichi one wish to make up for all of his bad luck, but when Keiichi wishes for Belldandy to stay by his side forever... the trouble begins. Can Keiichi keep Belldandy by his side, or will outside elements force her to return to heaven?
In both animes the girls are from different worlds. Although Shuffle! is more of a harem while Ah! My Goddess is more of a romantic comedy. Both are really funny while Shuffle! is more perverted and Ah! My Goddess has more harmless laughter.
Ikko is a Buddhist monk in training who works at his grandmother’s temple with six nuns -- six very attractive nuns. Though lazy, weak and unmotivated to learn the skills of a monk, amazingly strong holy powers sleep inside of Ikko that are triggered only by the awakening of his, shall we say, lust for worldly delights. A vengeful spirit is haunting your home? A flash of pantsu, and Ikko's your man. But therein lies danger; what really is the secret behind his mysterious powers? And how many hits to the head from angry, semi-naked nuns can a man take?
Both series follow a pretty basic harem plot, with the addition of magic and good vs. evil battles to keep things interesting. There is more focus on "dirty" comedy in Amaenaideyo!! than there is in Shuffle!.
