I'll be kind and start with the positive. There are a lot of options you can choose from when building a race, more so than any other race builder i've found. But it is potentially to the point of excess. There are certain areas where there are too many varying options when it could have been done simpler.
The part i found most frustrating is the way it's handled during the creation process. rather then functioning in a point purchase (i.e. i buy swim speed 30 for x points, then can increase or reduce it for y/-y points, it is package based. everything is to be bought in precrafted packages, which is fine until you have a specific combination that they don't have. At that point you either need to find the best fitting option or abandon that idea. Sometimes the option might be buried in there, but it has all these additional add-ons that are either unnecessary and driving up the cost of the package, or outright unwanted in places.
The part that drove me to actually make a review/response as opposed to just staying silent is there are some homebrew spells included in the book. At first thought i though, neat, wonder how those will work. Then iread them. a few of them were ok, nothing all to special or illogical. then i got to one. I showed the description to several friends i play with without showing them the entry in the pdf and asked them what spell level something of that caliber should be. The lowest response i got was a 5th level spell. It's a cantrip.
Going through i thought a handful of the numbers were a bit high or a bit low, or even inconsitent in places, but figured it was just me. but when there are such glaring overpowered entries listed in this, it makes me second guess how useful of a reesource this 'ultimate race creator' is as it calls into question how balanced a lot of it is.
If you want something wack and fun, if you want to make races for the hell of it, or you don't give a fudge about balance, then this is likely a 5 star product for you. This came from a place of love and passion, that much i can tell. While my review iis negative there is no denying the hard work the creators put into it.
We're sorry you found the book unbalanced and we try to be very responsive to balance recommendations. We're already hard at work implementing some changes for a V1.1. Could you tell us which spell was the issue for you? We'd be happy to revisit it.
