I honestly was not expecting so many random tables. Seeing as how I love random tables, that's a win in my book.
I love the options for changing things up a bit, even if I thought the layout of the scenario was fine as is.
The legacy characters were a really nice touch, as I wasn't familiar with them or their creators (I'd heard of Green Turtle, but was otherwise unfamiliar), so those sidebars were a great bonus.
If you want to run it with Savage Worlds Adventure Edition, you'll have to do any statblock conversions yourself. I haven't played around with the Super Powers Companion and SWADE much to see if anything wobbles or breaks when they are combined.
Despite how much I love Savage Worlds, supers gaming, and my Necessary Evil campaign, I'm not super high on Savage Worlds as my default supers system. If that's a stumbling block for you, there are three other systems linked above (ICONS is my preference of those three, not that you asked). That said, I actually can't wait to see what an Adventure Edition-compatible Super Powers Companion is going to look like.
The scenario is just what I like in a scenario: A strong skeleton with room for you to hang meat on the bones if you want to tweak it or expand it. And well worth it for the price, too.
