Having tried just about every 3D modeling software out there, free and otherwise, Maya has always been my favorite and go-to for anything even remotely geometric. That this is on steam for such a reasonable price is absolutely fantastic. The new features in this latest version specifically for people like me are awesome. I'll miss ncloth but that is about the only thing this version doesn't have that I enjoyed previously, and frankly, there are better programs now for such situations (ie. Marvelous Designer).
Opening this software as a complete newb to 3D modeling, I can understand why you'd be dizzy. There's a lot of buttons, tools and short cuts that I've had to learn over the years and I'm still finding new things all the time now. If you're serious about learning 3D modeling and you're looking for the right tool, there really is no other program on par with Maya. You're talking about a solid week of youtube tutorials and trial and error to learn enough to actually produce something of any value, especially if you're producing content for a specific engine or world... but it's more than worth the while to learn!
Autodesk, thank you thank you thank you for putting this on steam at a totally reasonable monthly rate. I am beyond happy to pay you this monthly subscription for this great tool instead of paying it to the IRS. Yes, self-employed artists, this is a muy, muy bueno tax deduction too~
EDIT: Adding a little to this after working in it more.
The current disappointment for me personally is the lack of native or properly working COLLADA support. Yes, you can export as FBX. Yes, you can use the FBX converter, but doing either and/or both of those seems to result in some wonky normals issues that I've yet to find a fix for. I've had to backwards import into previous versions of maya I have just to export to .dae.
I really hope autodesk addresses this given the significant use of .dae in the modeling/game dev world.
