any books similar to terror infinity, that are actually written decently by people who have a general concept of english?

That I know there is a fiction here in rrl called terror infinity side B, it's basically the same thing a the original but instead of movies it's anime, the MC is an otaku and the characters are different. but it is the same system with the lord god etc...
That would be the only english one that I know, and if you may be interested to know, like infinity terror is a chinese novel, exist a lot of chinese novel about the same genre, there is two predominant genre about it, "Infinity" and "Unlimited", infinity is the same as you saw in terror infinity, with a lord god, a team, mission to do to gain points in worlds, and survival, and unlimited would be an "personal" lord god, basically an system that let's the MC shuttle between worlds, with sometimes exchange functions or only an lucky draw that it all depends on lucky to see what he get, normally this type of novel is more relaxing and rather than the survival theme it involves more travel between world, fucking who he doesn't like in the world, trying to woo the actress that he likes etc...

Here is some chinese novels about this kind of genre:

Well, those are some chinese novels being translated or were being translated, don't know if it was dropped or what. if you want I could tell you about some more stories as I personally love this genre and already read like 30+ chinese novels, but those are in chinese so I think that you wouldn't be interested in them so that's all, bye and good luck in the search for a good novel to read.
