Plenty of massively multiplayer online role-playing games attempt to fulfill the promise of easy-in, easy-out gameplay to appease folks that don't have a great deal of time on their hands and just want a quick fighting fix. Rift might be the first MMORPG to deliver.
If it works as advertised, that is. From the look of it, this new Instant Adventure feature is a large ongoing battle for character levels 45 to 50 that scales as players enter or leave, allowing them to pop in and out of the action with the click of a button.
Other games have features somewhat similar to what Rift is adding, but those normally involve getting in a queue and waiting or dealing with party balance issues once you get there. Instant Adventure, on the other hand, is just that. Click, click, boom. Well played, Trion!
Update: The feature is actually named Instant Adventure. Fixed the text to reflect this.
