I'm not really a collector, in the sense of trying to collect everything for a given system. I just enjoy good games. I do buy complete in box items exclusively, though. The systems I collect for are: Atari's line of 8-bit computers, plus their 2600 and 5200; Mattel's Intellivision; and Coleco's ColecoVision. I also have a Playstation 2, a Wii U, and a 3DS, but I don't really collect for them. Outside of video gaming, I enjoy theme parks, watching movies, playing tabletop board games and RPGs, and reading science fiction and fantasy books.
Yes, Intellivision threw down the gauntlet to Atari with those awful controllers that screwed up an otherwise awesome system. Atari, motivated by this challenge, decided to create the 5200 controller and the new Champion of the-controller-that completely-jacked-up-a-system was annointed.
