I'm not sure I put this right. It's a MMORPG, so I guess it's flash.
I think it's a fantastic game because it's very big, update often, free, grows fast, have great graphics, you can change it's language and it don't require a very good computer.
Here's a couple of screenshots and trailers of it. Here's a link to the Europeran server Heredur.
Yep, like I said. If you want to play through and get a higher level without the pain of dying each 5 minutes then join a strong guild (may not be the fun to run through instances with high lvl guards who hit everything for you) or buy Adermant (game money) to get those crystals of truth or direct gear.
