Excellent! The Ultimate Edition of BASH is superior to its predecessor in every way possible. The book has expanded from 32 to 137 pages, with more powers, a section on super-hero genres, and a killer layout. If you're new to BASH, it's an easy to learn system that plays very fast but still manages to have enough crunch to keep you interested. The basic mechanic is rolling 2d6 and multiplying the result by the appropriate stat (Brawn, Agility, or Mind) plus any applicable modifiers and beating a target number. Simple and easy.
Characters are built on points. These can range from 20 points for Mystery Men to 60+ points for Cosmic-level heroes. While there are plenty of options here, it won't take you hours to build a character and you could jot all relevant stats down on a 3x5 index card.
If you owned the previous edition of BASH, you should really get the Ultimate Edition. The layout is outstanding, the art is bright and colorful, and all the extra new stuff is worth the price of admission.
As far as super-hero games go, BASH Ultimate Edition is my go-to system. Fast, easy, and fun.
