On ABZÛ we ripped out multiplayer and lots of other cruft from AActor and UPrimitiveComponent - dropping builtin overlap events, which are a kind of anti pattern anyway, not only saved RAM but cut a lot of ghost reads/writes.
Thank you for ABZÛ! My daughter has played it at least ten times. And when she wrote a letter to your team for a school project, you sent back a t-shirt and a soundtrack CD. We've listened to that CD for hours on road trips, it is a great soundtrack.
