I've actually been playing DDO since october, i have to say it is alot of fun. The best part about the free2play aspect of it, is that you can actually max out the level of your char without spending a penny on the p2p stuff. They also have this thing called the DDO store, basically you can buy adveture packs and other things that are not included in the f2p account using DDO store points. These points can be baught using money but you can also earn these points through what they call favor rewards ingame. As a matter of fact, if you realy wanted to put the time in you could earn enough favor rewards to buy most of the p2p content ingame without spending a penny.
