I read this one after reading Fate Core so.
I liked a bit more the reading of this Fate book, the rules are much better explained than Fate Core and the book is less big to read (60 pages only).
The issue is I don't thinks this book is useable if you want to use the thing called Extras in Fate Core because they aren't present here. If you create a setting which does not need extra, it"s fine but if that's not the case, well there are no explanations on how you deal with it. If you never read Fate Core before, you don't even know that you lack tools to improve your Fate Experience.
Still the book has plenty of optional rules so...I think you better with Fate Condensed than Fate Core.
