RIFT is on sale for $0 (that's not a typo!). Does not include any game time:

just to clarify, you will have to enter your credit/debit card info before completing the purchase, and game time is acquired by monthly recurring subscription fee.

RIFT Lite lets you play for free up to level 20, with no charge or time limit. this looks like more of an extended trial as WoW did recently. i doubt much can be done at level 20, though.
