A great comprehensive book I feel like I rarely see on Sega Genesis, usually it's the Nes that gets all the attention. Also great to see the Sega CD and 32X included instead of wasting time on a separate book. The format is nicely laid out with 1/4 page for each game unless its a popular or defining game which gets half a page.The descriptions were well done for the most part, there were times it seemed all was written is the generally useless plot instead of going over other aspects. Largely that was the case, though maybe some games just don't have much that can be said. While there is some humor mixed in, it doesn't come off as trying to be over the top. What I did find annoying was the overuse of the phrase "because of course it is" or some variation, usually in regards to plot. If it was meant to be funny it just got old after the first few times, and really why are we are overthinking some 16-bit game plot like it's so absurd for certain games anyway. It felt like a pointless addition to only waste space to fill. There are also a slew of sports titles with and without team or player licenses which was explained in the first instance. Yet for almost every single release thereafter he thought best to reiterate that a lack of a players league means no official players, for every single sport. Totally needless as another space filler, not to mention the frequent virtue signaling throughout that has no place in an encyclopedia. I will say the extra facts were informative bits I was unaware of.I did read the kindle version only, there was more than a handful of spelling mistakes, missing words or punctuation that could have used another proofread. At the end of every description was an N not sure why, but sometimes it would be after the period but mostly over the last word or right over the period. Unsure if it this is something only with the digital version, but I am using the most recent Kindle release.Author makes a claim to not inject reviews as it's an encyclopedia format, but then talks about arbitrary game prices and rarity on a few occasions, that I think doesn't need to be touched on here. Considering there are not really any complete books like this on the Genesis it does what it sets out to do. To be complete would have been great to see all the controllers and accessories covered too, such as the Activator and Menacer so that takes it down a bit for me. These are things that can be updated in a future revision that should also fix the spelling and sentence errors, rewrite the sports reviews to be less redundant, kindle issues too. Regardless of your stance on things, I read a video game book for the facts and enjoyment, but having to read about this guy being offended about things like Indians in Sunset Riders and the like has no place here. If you can get past all that, still good for a fan.
