There will be people who will make one, because they are interested in this
Yes but it will be very silly cause I'm guessing that they will create a high-rate one and you will get everything in 2 days ... then for 1 week you pvp like crazy and after 1 more week you delete the game ...
I don't think there are "public" server files already, and emulating the game will take quite some time (as an example look at the Tera/Blade & Soul P-Server).
And i highly doubt it's worth to make a vindictus private server.
