I've got a few homebrew games, but I'm not typically impressed with them, so I haven't sought out a lot.
That said, I did contribute to the kickstarter for Tanglewood because the original demo was so impressive. I've also been meaning to buy a copy of Owlia because it was so fun watching that game come together. If a modern developer of retro games seems to be doing something really cool, I'm interested. But there just seems to be a lot of shovelware, too, so I find myself being pretty restrained.
