Heroforge first, now Metacreator
I agree- Heroforge was never complex or difficult IMO. When we first began using it, my daughter was 9 - I didn't even need to explain it to her. It was easier than reading through all the class/race/feat stuff in the book.
I recently switched to Metacreator - a nice, no-frills product, that (from my use of it) is not only quick for character generation, but makes tweaking, changing, and/or adding stuff super easy. I'm using it for a D&D game as well as a Savage Worlds game. In both cases I am using a home-brew setting (no other kind for me) that required a bit of hands-on when it came to controlling all the different junk I was making. With Metacreator, it works great for organization, you save your own data in its own place (instead of making numerous copies of a spreadsheet). A lot less HD space (though HeroForge never seemed too huge), excellent support, and a great group of users to ask questions of.
Though MC has a short learning curve (depending on the template) of about 15-30 minutes, it is by far the best product I've used for all aspects of character/NPC/Monster/Magic/Spells/Items/Gear/etc/etc management that I've come across in a long time. It is much more than just a character generator!
Good Day!
