Darkfall is having a 7-day trial, but it costs $1 dollar to get it.

8 hours in, and I think I'm hooked. I started a Human toon in Sandbrook, named Cerlon Lockett.

The gameplay reminds me of what The Elder Scrolls 4: Oblivion has in the way of Massive World Areas to explore, but it's more like they added Multiplayer to it.

Also to note, though, is that if you die, there are very big penalties, as in you lost most of your stuff, but you retain some gold, an item or two, and your "Starter" weapon or weapons if you bought more starter weapon slots.

A good thing, though... It runs on my current computer, and I only had to turn the shadows off to get it to run close to perfect.
