NES, SNES, GBA (I had to sold most of my GBC collection along with the console itself but I managed to recover about all the games I really cared for, and since they work for GBA, there´s no need to re-buy a GBC), NDS, GCN and about 2 weeks ago I was able to purchase a Wii.
About non Nintendo consoles, I always wanted to have a SEGA one, being my 2nd favourite company, but as a kid, you don´t have all the money you want to spend, so I had to go with only one console, which always has been the Nintendo one for each generation because my bro prefered it over the sega ones. Not that I complain because I´m such a huge Nintendo nerd and watching at SEGA´s failure, I am glad I stayed with Nintnedo, although since I really like SEGA´ games, I will probably go on a retro mood when I have the money and buy a MegaDrive/Genesis and/or a Dreamcast.
