+ PROS AND CONS OF EACH GAME +
I've actually been meaning to do this for a while ago, but somehow I've just strayed from doing it. I find it troublesome that Aksys Forums don't allow you to edit previous posts, so this one will have to do for now :/
Note - The following are just my own perspective on the positives and negatives for each game. You may or may not have a different opinion to my own.
1. Hakuoki: Zuisouroku (Fan Disc)
+ PROS +
* It's definitely something for the Otome lovers out there, since it includes all the romance that the first title (Demon of the Fleeting Blossom) didn't have.
* It's meant to be played as an "add on" of the first game, so I think chronologically the fan disc should be released next.
* It's just something light, fun and fluffy - something which anyone can enjoy. You don't need to play the first title to have fun with this one, although playing the first title will of course, help you understand the events of the game much better.
* Loads more extra CGs from the original artist (Kazuki Yone). Her art is just beautiful.
* For people who played the first title, this is just some extra "moments" between you and your favourite bachelor, and just makes the whole game so much more enjoyable.
* It just makes the first game feel more so complete.
+ CONS +
* When viewing it as a stand-alone game, there really isn't going to be any new content story wise. It's basically the romantic moments in between the main storyline, so you're really not expecting anything new in that department.
* Length wise, then it is shorter than the first title because there really isn't any new content (as I said above).
2. Hakuoki Yuugiroku (Mini Game)
+ PROS +
* This is definitely the lightest and fluffiest game in the series, and its packed with loads of fun events and mini games.
* The chibis are just adorable, but not only that - they also included some bonus character scenes with the original art from the first title, with the same artist.
* Art wise, then it's the best of both worlds (both chibi + normal CGs)
* For age demographics, then this can be played by all ages.
* It's just something fun to play when you're killing time, and it mostly focuses on the humour aspect.
+ CONS +
* The length of the game is definitely disappointing in comparison to the other games, since it's only 30 mins per character path. In total, the whole game can be completed in an hour.
* There is little to no plot at all. It's just basically the shenanigans with the different characters of the Shinsengumi.
* It really is just a random add on, with not much substance.
3. Hakuoki Reimeiroku (Prequel)
+ PROS +
* This is a completely different story, and can definitely be enjoyed on its own without purchasing any of the other games.
* Length wise, then its actually longer than the original title.
* Unlike the other titles, this is an actual Visual Novel. Meaning, it mainly focuses on the immense build up of story, rather than anything else.
* It's something that can appeal to all audiences, since it is not an "otome game" like the original.
* It gives players of the original game an insight to all the characters and their inner conflicts, whilst explaining the origins of the Shinsengumi.
* Not only that, but it includes the "true epilogue" of the paths in the original game, so we end up knowing Chizuru's true fate with which ever guy you chose.
* Loads of beautiful art as always, from the original artist.
+ CONS +
* The text heavy-ness can be rather daunting, and it's actually much darker (angst and theme wise) than the original title.
* Otome lovers may feel deterred by this title, since it focuses on forming friendships with each of the members of the Shinsengumi. You play as an all new guy character, not a girl.
