Guild Wars 2

It could be like the opening week where you did a new build every night at midnight, except you wouldn’t have to actually patch anything. It would just reset things. The purpose being to fix bugged events. However, this wouldn’t be necessary if the game had WoW-style GMs who could respond to tickets and reset events themselves.

EDIT: To keep this from messing up people’s dungeon runs, you could make it affect just the open world and not those in instances.

But a scheduled reset would also have other uses. It could randomize the resource nodes. It’s so tedious right now. You find out where the orichalcum is, and then go there every 6 hours and know it won’t be anywhere else for about a week. Also it would help slightly with the horribly inconvenient respawn timers on rich nodes. Its bad to mine one at 11pm and know you will have to log in late again next time, or skip it for a day.
