tbh, controversial opinion, but I don't care too much if it's traced or not as It doesn't look the same, and FOBS is way higher quality anyway. I just see it as more content for us to play with. Games like FOBS are rare as it is. Maybe this new game's dev can get experience and make more original looking designs
in the future, IDK. I'll just continue to support fobs. I am not saying that I am in favor of tracing and stealing, just that it looks different enough to me, and its more content. Succubus Affection looks similar to Zell's work art wise, and I remember another dev with a similar art style. Now, if it was a rip off copy of FOBS with the same scenarios and everything, I would be upset.
I know that SA's dev has worked together with Zell.
