This DLC revamps Persia and the surrounding factions. I personally like what it adds.
If you aren't playing in this area feel free to skip it.
If you like to play in this area I think you will find the DLC fun and a good way to explore the area.

It's really simple but has lots of jokers to modify how you play, it sucked up a good 20 hours of my time.

I bought this game *very* discounted (under $5), and for that price, this is a great match three game. But that's all it is. The description touts "saving your village", which is the loose plot, but the buildings in your village are nothing more than trophies achieved after earning enough jewels from boards. The "trophies" have little animations, but are not interactive- you don't even get to decide where in your village they go. The match three boards themselves are challenging enough, but I find them repetitive and no longer interesting after about board 75. So, good price for about 75 boards, but don't expect more.

Galactic Paragons while adding a slight power creep, also adds new and improved leaders. Finally they matter, they are no longer no-names you'll just roll every single time. Now each leader can get specialized and losing them can hurt. You also get council agendas, which give you some more stuff to do in peace time.
