VN Ren'Py Grand Duke Valeran - Building a Harem in Another World [v0.4.6-public] [Mr.I.Game]

[mr.i.game]

Overview:
Welcome to the magical world of Grand Duke Valeran, where elves, beastmen, dragons, and even gods truly exist.
You will step into the role of a young man who, after being struck by lightning while fapping, is reincarnated into the body of a young marquis in this fantasy realm.
And just like many other protagonists, you carry the heavy burden of saving the world.
Follow our hero's journey as this ordinary guy figures out how to save the world. This is a tale of adventure, war, and intrigue. And trust me, it won’t follow the usual tropes. After all, a protagonist isekai'd while fapping has to be different from one hit by a truck, right?
Note: This game is written in the comedy genre, featuring humorous situations that may sometimes feel over-the-top for some people. If you consider yourself a serious person who isn't into a game with a lot of comedic moments, you might want to skip this one.​

And with that, you’ve been isekai'd.

....thx for the share....good luck....

 

[Macgamer]

Looks like fun

 

[rKnight]

You've been isekai'd. After being isekai'd, you’ve inherited a noble title and become a Grand Duke.
Save the world and, along the way, build a little harem of his own.

MC: "Good bye, real world..."

THX for the share...

thx

Thank you all for your support! I’ve revised the overview. Reading the old one again, it just felt a bit off!

 

[MOGGERrn]

So......is this a sandbox type game?

No, it will be a visual novel, but with only one ending. However, there will be different choices for side girls and side events, though these choices won't affect the main storyline.

Thank goodness (sandbox suck XD) and.......who cares about other endings when there's a harem ending?

Haha, I don’t know about everyone else, but when it comes to adult games, I can only play them once, maybe twice or three times at most. I hate games that force you to replay multiple times just to unlock all the endings. And I especially despise those games where you have to unlock 5 or 6 endings just to get some half-hearted harem ending!

Anyway, back to the topic. The truth is, I plan for this game to have a long storyline, and I simply don’t have the time to write two or three different endings. Plus, for the reasons I just mentioned above, the game will have only one ending. =]]

I mean, why choose one when you can have them all, and yeah, having lots of LIs and making us choose only one at a time frustrates me a lot. I would rather play a game with one LI than a game with multiple LI without a harem ending.

judging by the tags theres no H content yet? Would probably be a good idea to put future tags in so we know what to expect

Great idea! I’ve added some planned tags.

H-a-isekai

Here's a good example of a detailed gene section from a successful first title developer (He has 1600+ monthly subs on Patreon)

Wow, that’s so detailed! I’ll take it into consideration and add more later, probably starting with a few 'never added' tags first.

Wet nurse? The author's taste is quite bold, but I like it!

Need to beat up that disloyal cousin and teach her who the boss is
