If you speak of another version where the spider exist for those that wish to have spiders in the game then I call it modded, since it's not a feature that existed in the original version that REMAKE are based on and since it's not a feature that the devs planned to place in the REMAKE game because of obvious reasons that they have already explained!!
Besides while you could understand that the + means it's a different version of REMAKE, would everyone understand that this is not the original version of REMAKE or would they think there is something else added on the game and install that version thinking it would be fun only to be disgusted or similar when they see the spiders that they wanted to avoid in the first place, that's a possibility even IF the devs where to make it and add into the description that to help those who wants nothing to do with spiders to avoid this version of the orginial game!!
Of course that IF the devs where to make such version of the game to let those that wants spiders to have a version that they can play, since I imagen that the game already takes lots of times and making another version with features that originally didn't exist or was even planned to be added would probably be a hassle!!
