It’s been a while since I finished MOST of VitaminZ (still haven’t got those bonus events!), and I think I can finally do a kind of final review.
If you haven’t gotten VitaminZ OR X, go out and get one! They are both awesome. The system and story might seem boringly similar if you haven’t played both, so here’s my rundown on the differences:
Characters
The characters in both games are totally different. You might think that the student in Z with a certain teacher from X would be similar, but it’s only a surface thing. For example – Both Tenjuurou and Tsubasa are rich heirs to a conglomerate, but Tenjuurou, unlike Tsubasa, has a great family, and doesn’t care at all about “high-class” stuff like Tsubasa did. Their personalities are almost opposite.
I enjoyed all the characters in both X and Z. Even the two characters I wasn’t looking forward to, Yakumo and Arata, had me really liking them in the end. If there’s an overall difference to X, in Z they’re nicer to the heroine in the beginning, though they still don’t really trust her until later. I also liked this heroine better, she’s not as ditzy as X’s heroine.
Depending on who you liked, and what you liked about them, in X, you can probably find someone in Z that has that aspect. If you like Tsubasa’s arrogance mixed with cluelessness, you’ll probably love Kei. If you liked Hajime’s ‘bad boy’ aspect, you might go for Nachi. And of course, if you like cute boys like Gorou, Yakumo will definitely be your pick.
Apart from the A4/P2, there are of course the B6, GTR, and the president & VP. Personally I wish the GTR had had a little more airtime and the B6 a little less, but with the extra ‘ura’ route and the append chapters, if you do a full complete they still have a lot of material. I’m also hoping for an adaptation like VitaminX Evolution to flesh out their stories a bit
Plus, if you’re a huge fan of one of the B6 then you’ll probably be quite happy. Another thing that I like is that there is no flirting or anything between the B6 and the heroine, they still all like X’s heroine.
Plot:
The overall goal is the same, but in VitaminZ the school president actually has a sinister motive in picking an inexperienced teacher, and so the overall plot is a little more complex and interesting. The events happen mostly the same way no matter whose route you’re in, but what you actually see as opposed to what goes on behind the scenes, and the details that you’re shown, are always different.
You have the same school events as in X, but in Z there are also assemblies where things happen (mostly in the P2′s routes), and there’s a summer ‘study camp’ (gotta have that kimodameshi doncha know!).
Gameplay:
VitaminX was quite easy to play (in terms of saving etc) and VitaminZ is apparently even easier. The setup of tsukkomi/through and month-end quizzes is the same, but in VitaminZ you have to pass a special quiz in Chapter 11 to finish a route, so it might take a couple tries. The character designer’s style evolved since X; though it’s still obviously the same artist, I like the newer designs better (Chisato, マジでかっこいい!!)
Other differences:
I think VitaminZ has a little more romance than X, in that the characters all show in little ways that they like the heroine earlier, and (maybe) a little more obviously than in X. And though each route has some drama in it, I don’t think there’s quite as much angst as in X (not that it was huge there either).
So. If you loved X, I think you’ll love Z too. Which one you like more will probably depend on your favourite character. And if you didn’t like X, because of the gameplay or setup, you may not enjoy this either. And if you haven’t tried either, go check out the characters on the D3 site (Vitamin X / Vitamin Z) and try out whichever appeals to you most! Although, if possible, I’d recommend playing Vitamin X first, just because you’ll then understand the B6 interactions in Z more, and it makes Z even more fun ^_^
Oh, if you choose Vitamin Z, YesAsia, has the Limited Edition on sale for cheaper than the regular version! In addition to the limited edition box, you get a drama CD and a calendar.

First time to comment here ^^;
Thank you for posting a review on VitaminZ. It makes me want to buy the game too. I only have the VitaminX evolution. (I like the P2 guys. I have a thing for twins.)
-I hope it’s okay. But I have a question about VitaminX. (tried searching the site for sending pms) I wanted to get Tsubasa’s normal, heavy and core in Chara Mania. I already got the normal, perfect and dream end but I still only have lite. While in Ootori’s I got normal and heavy when I finished perfect and dream end.
It’s ok
Have you gotten both of Tsubasa’s zappings? That’s the only thing I can think of offhand that might affect his chara stuff.
The love and study thing right? Yes I got them too. I have a cheat on when to use the actions (can’t remember the site though. just saved the cheats on pc)
I saw something like append end at the bottom with a b6 guy+month on it. It has something to do with that right? O_O
