When I\'m online it seems that everyone has agreed that using the exclusive locking workflow in source control is a Bad Thing. All the new revision control systems I see app
On an open-source project like a game, it makes sense to keep images under revision control, and those are nice to be able to lock (Subversion supports this). For source files, it's better to get into the edit-merge work flow. It's not hard and increases productivity in my experience.
