If I had the rights to CF, first thing I would do is have a sitdown with the staff. Get up to date on the project board, whats in the works, and see whats tasked out where. I wouldn't come in and try and boss things around, they know how to run the heavens better than me. Instead, I would use a million or two of the money to create salaries (maybe not huge ones) to the CF imm staff. A little cash on top of everything would REALLY make people go that extra mile when they are maybe otherwise feeling drained, down, or unappriciated for the work they do. I might make a special exception, and throw someone like Zulg a mil so he would have more time to work cf. I would use money for advertising, webdesign, and probably a small marketing team to bring in new gamers.
And yes, Silent tower and Hell would open, and stay open.
Scarab would be tasked with following up his inferno with Paradiso :)
Daevryn would have to change back to Nepenthe. I liked Nepenthe the character.
And most of all. Entropy would be back, and I would be its immortal :)
