eh, i have to give this game a little credit.
most of its elements seem purely based off of common rpgs, like the health, magic and experience bars. the crafting system is fairly simply and i dont think you could say it copies one specific game.
the creator seems very mature about how he replied to some of those youtube comments so props to him on that, he gave answers only to those who weren't directly insulting the game and even complimented someone for giving some good suggestions, even though the suggestions were put rather rudely.
though what i agree with is that the game looks far too much like cube world. no doubt vox was partially inspired by it, but i feel that people are calling it a ripoff just by the cover of the book. cube world isn't entirely original itself, mind you, but on the other hand this game seems to lean a little too far towards the way cube world plays. the vox website was redone in april this year so i can't tell how far back it goes it development, only that it was v0.38 when the website reconstruction was finished.
