I play it all really. I am more so a fan of retro than anything else. However, I do enjoy modern gaming too a lot. I do not own a XboxOne, a PS4, or a switch. I do most of my modern gaming on PC now of days. I'm not interested enough to go out and buy a XboxOne or a PS4 right now for only a few games that I might play. So I rather wait till later to buy the console when it's cheaper. However, I am greatly interested in the Switch though. I plan on getting one of them sometime in the near future.
For Retro my favorite console has to be the SNES, then the PS2 right after. I actively collect games retro games for NES, SNES, PS1, and PS2. I will go out of my way to grow my collection for these. I also collect Japanese game too for these systems. I have a "modded" SNES Jr that i play Japanese games on. I do collect for other consoles such as sega, n64, gamecube but i don't go out of my way for these games though. If i happen to see games or something i will pick it up if it's not too much. Im hoping one day that i will run into a 3DO, Intellivision, or other consoles that weren't big in the mainstream as others where.
