I've been going for complete sets on all SEGA consoles since about 2012. I just completed the 32x set in September with Web of Fire. I haven't been going strongly though for a while. I mainly chose to go for a complete set just because I enjoy the consoles. It also kind of allows me not to load my house down with more consoles. If I wasn't going for a complete set, I would probably own a NES, SNES, etc etc. But knowing I have the complete sets to work on, I'm pretty content with digital for everything else whether steam, emulators, android, etc.
