If you've ever had an Age of Conan account and you've checked your email in the last day, you probably know by now that you can revisit the game for free through July 22nd. According to developer Funcom:

The re-evaluation offer is valid from July 8th to July 22nd and is available to anyone with a closed account in good standing. Reactivating at any time within this period will open for two weeks of free play - regardless of when you choose to act within that time period. There are no costs associated with this offer or any subscription obligations. It is also important to note that the free trial campaign will temporarily be closed to ensure the best play environment for all returning players.

If returning to Age of Conan isn't your thing, you can return instead to Lord of the Rings Online (pictured) as of today. Developer Turbine's offer to let you come back and play for free lasts through July 15th. Furthermore, you get a +25% experience point bonus for the duration. Details available here.
