The Press-MDA has dropped for Tabula Rasa, and Michael of MMOGNation has laid out his thoughts for us.
I can't say much without breaking the NDA myself, since I'm not press like Michael. I can however say that I agree entirely with his assertions. So go read the article.
The part about subscription charges is right on the money from my viewpoint. Ugh... I still can't say more. My own full impressions will come as soon as they let me loose. So until then, read Michael's and enjoy.
