NextGenBooks.com (yes, but stick with it) has launched Warrior Quest, a browser-based single-player RPG "in a similar vein to classic games Dragon Quest and Phantasy Star".
It's free, playable in a window on the website, and NGB's claim is that it's optimised to run on Wii and PS3 web-browsers, with a PSP edition due to launch this month.
One of the reasons why it's suitable for these platforms is that, for now at least, it's a bit on the basic side. That's why NGB plans to include new and revamped animations in its first content update on 2nd April, we'd wager.
Also in that will be new Battle Cards (the game uses a card-based battle system), and the first bit of a new story mode.
Further infusions of content will then go live monthly "until the end of this year".
At the moment, you play as a young "Battle Master" exploring a fantasy world, beating people and things up, upgrading your skills and unlocking new bits of the map.
NextGenBooks.com says it plans to do more content like this in future.
