Oh I mean what exactly were his deliberate errors. I don't know anything about the game, so I can't really tell.
Looks like they just changed the wording deliberately to say the same thing.
But to be fair, here is the thing with a guide like that....
If you are making a guide as to where bosses or items in a game are, then everyone making that kind of guide is going to have the same information on it because the bosses location in the game isn't going to magically change from guide to guide. Same thing for strategy. Like if the bosses weakness is Fire, then every guide will point that out.
So I don't think he really has anything to go on. Though the big company did likely steal it, because it is cheaper to steal from someone who's done all the work than to pay an employee to sink 200 hours into a game and write the same guide that wont have any different information on it anyway. It's very common in the guide sector of the internet that everyone steals shit from other people.
At least it isn't a review this time. Because that's a different thing altogether.
