Ask to be acquired?
jeromec: I just had another idea. I still think approaching them for acquisition is an option, mostly because I don't like businesses dependent on other businesses (for precisely this reason). However, an alternative route may work better. I wish I had a fuller understanding of text based RPGs like MobWars because they are making an absolute killing. I tried one out once, but just couldn't understand its draw, otherwise I'd create one in a heartbeat. But obsidianportal.com seems similar to me, just based on D&D copyrighted material. Try to brainstorm out a text based RPG that would appeal to D&D'ers but with your own material. You already have a community to sell it to, and it might grow to be worth far more, and you own all the IP.
