I've been a huge fan of Rifts since highschool back in the 90's. A few years ago PEG Inc picked up the license and created a Savage Worlds conversion of it. I couldn't be happier. I love the world, but was never a fan of the Palladium system.
Then Savage Worlds announced a huge version upgrade called "Adventure Edition" within about a year of Savage Rifts coming out. The team behind Savage Rifts decided to create completely updated books for the new "SWADE" ruleset and upgraded the electronic (PDF) copies of the books for free.
What an outstanding team! Of course I backed their kickstarter again. This group has won my loyalty for life at this point.
On that note though, their character sheet is severly lacking. So I went and created a character folio sheet.
--Update: I have temporarily removed the download link for my sheet. I will have another update soon.
