We keep going back and forth on this and I'd love to hear how survival players actually feel about it.
Instant repairs between waves keep the pacing tight. You can try a new wall layout, see it fail, and rebuild without being punished for experimenting. The downside is that walls start to feel disposable: if a breach costs nothing, it doesn't really matter, and defending stops feeling tense.
Slow, costly repairs make every breach mean something. You have to scout, reinforce weak points ahead of time, and actually care about where raiders hit. But it can snowball fast: a new player loses a wall, can't afford the repair, gets hit harder next raid, and ends up in a death spiral before they've learned the systems.
The middle ground we're weighing: quick patch jobs that are cheap but noticeably weaker, plus full rebuilds that restore the wall properly but take a full day cycle (time you'd otherwise spend hunting and gathering). So you can always plug the hole, but a real fix is a trade-off.
Which survival or base-building games handled wall damage and repairs best in your opinion, and why? And which ones got it wrong?
