Scion was being touted as a "Modern-Day Exalted." It is more like a mix of Aberrant and Exalted with little more to offer than an immediate gaming fix. Designed as a finite story and game line (3 books planned total), this game is a solid basis, but not much else unless you like playing pregenerated stuff.
It's a rules-lite version of Exalted for the most part, with a little bit of Aberrant thrown in. Six pantheons provide a very global basis for characters to start with. Chunky rules are easy to understand. Comes with an adventure AND pregenerated characters so you can jump right into the game and genre, and the opening fiction additionally focuses on one of the pregens. Some good "stock" badguys and updates from mytholoogy
A min-maxer's dream. From the (IMO) overbalanced Mega-Attributes (called Legendary Attributes) to a gift/charm system which allows you to pick and choose whatever you watn, to two powers that force the GM to tell you what's going on and what WILL be going on, the game screams for two or three twinkie players to build unstoppable monsters. In addition, there isn't much provided beyond "regular" opponents. This doesn't just mean bigger, badder monsters, but none of the enemies (no less then the sires of the Gods, the TITANS themselves) are detailed outside of a blurb for an NPC. Where the Gods are well-thought out and given plenty of background, individual titans and their plans, desires, methods, etc. are virtually unseen in the book other than vaguely menacing references and a promise that no PC can take them on (yet.)
A pregenerated adventure designed for the pregenerated characters which at least 1/3 of is directly tied to the pregenerated characters. The book's "maybe-maybe-not" approach to the game's backstory (Ex: Want more pantheons? Build them. But then the game changes because the Gods are stronger. But maybe not. But maybe yes. We don't know, and we're not going to give you more). White Wolf's total lack of proofreading for grammar and spelling. Poor layouts that seem outright wasteful in certain areas due to whitespace unused. The fact that the book is all BLACK AND WHITE when Exalted is totally in color.
In all, it's a noble effort, and one that might gain prestige and much-needed background with the release of the other two books, but the game itself takes an almost hypocritical stance on backstory (such as the aforementioned thing with the pantheons, and passages in the book which say that you, the GM should do the research for this game, seemingly because the designers decided not to - like with the lack of ANY material on the Titans).
In addition, this game is practically designed to be min-maxed, and without a strong GM control, players will surpass all but the most specific or oblique threats with relative ease. The fact that the book allows you to purchase the MAXIMUM LEVEL OF POWER OUT OF THE GATE (at the cost of all your bonus points) because it's necessary to get the amazingly-powerful Legend Attributes at their highest levels and then tells you that the next book covers the next power level (2 months in the future at least) is poorly-done planned obsolesence.
