On.System Architecture
System Architecture (and it’s subfield Software Architecture) is a discipline which is surprisingly poorly covered. In a sense, it is still more an art than a science, and usually requires somebody intimately familiar with practical systems, to tell what’s to do and what’s to avoid when building a system.
IT Hares have lots of experience in both Software Architecture and more general System Architecture, and are trying to share their knowledge (and more importantly, their feelings) about them.

If you disrupt the game-event-currently-in-progress for more than 0.5-2 minutes, for almost-any synchronous multi-player game you won't be able to get the same players back, and will need to rollback the game event anyway.

However, keep in mind, that all fall-tolerant solutions are complicated, costly, and for the games realm I generally consider them as an over-engineering (even by my standards).

After your logic has failed in production, you can “replay” this inputs-log on your functionally identical in-house system, and the bug will be reproduced at the very same point where it has originally happened.
Another Quote:
You can implement your Finite State Machine as a deterministic variation of a usual event-driven program
