This review is addressed to anyone who plans to use this tool for game or mod development. If you're looking for software just to mess around with on its own, then you may wish to look around for another point of view.
If you know what you're getting for your money, and understand the purpose for which you're purchasing this software, then it may pay for itself after a few short uses. I would first like to point out that my "0.8 hours on record" is not accurate as the desktop shortcut for this software (as well as blender and some other applications) does not open through steam by default. More accurately I have used this software for about 10 hours.
Creating a character in Fuse is very easy,and while the default proportion options for your characters seem limited at first, you can modify that in the program's preferences. The clothing options are fairly limited, but as I am primarily using these models as bases to modify later, it's really not that big of a concern. One nice thing about the clothes however is the ability to recolor them as you see fit, so you don't have to go with the defaults. Also, after downloading the model you will have UV map available to edit your your leisure.
The character creation itself in Fuse isn't all that special when compared to open source software MakeHuman, but where Fuse really shines is the rigging. Rigging a model can be a time consuming and tedious process that will really dig into a indie developer's or modder's time, especially when working with numerous characters. With Fuse you can simply upload your finished model to their website, and it'll be rigged within a minute or two. As I understand it, it was only recently that they started allowing unlimited free rigs, which now makes the software infinitely more useful.
Once your character is uploaded and rigged on their server, you are given the option to apply some free animations to your character (which quite honestly are a bit underwhelming), purchase ones from their asset store, or just download your rigged model. The prices on the store seem fairly reasonable, but so far I have just download my rigged model and animated it myself later. If a time comes when I am having trouble getting an animation down, or just want to save time, it probably wouldn't be a bad choice to jump back into the store and buy a couple of their animations.
But you may be asking, "if I am making a game or mod to sell, do I really want to use a character creation tool with such limited options when compared to working freehand?" While it's ultimately up to you if you're going to use the characters as is, I find it incredibly useful to use the finished models that I get from Fuse as bases to modify and expand upon in separate modeling software. Being able to get a decent looking, fully rigged model into Blender for editing in about 15-20 minutes is nothing short of incredible.
There are a couples things I would like to see added to Fuse later down the line, such as being able to export the model with a blank (though already defined) UV map, so that I can more easily modify the skin of the model once it is in blender/photoshop, or perhaps create models with an odd amount of limbs/features for more interesting creature design.
tl;dr If you're a small developer, this software is absolutely worth it for the rigging alone. MakeHuman is still a great program, but being able to have a fully rigged model that is ready to modify within minutes is an invaluable resource. Making unlimited rigs free was the best decision they have made yet.
EDIT: I have modified my original review to reflect a correction from a developer comment. Originally I wrote that the editing of proportions was very limited, but as it turns out it is in fact possible to modify the limits through the programs preferences.
