Well let's see. For me, it's PS2 (original), PS3 Slim, PSP (both original and a Slim), Sega Genesis, Gameboy (very original one, Color and Advance SP) and mostly old stuff like DOS games and Windows 95/98 games for PC.
A friend had let me borrow and allowed me keep his SNES for quite some time but I decided to give it back to him since I didn't want to hold onto it anymore.
The rest I don't own or play unless you count stuff like running emulator software programs, but I hardly have time for them anymore these days.
Interesting dilemma here. Games now have better graphics and voice production more than ever, some of these games damn near feel like movies! Which is very awesome. Also the feature of online multiplayer with live voice chat takes multiplayer gaming to a level that I am envious of the these kids and teens of! :-P
However, paradoxically, somehow, the overall "fun factor" of current games to be lower... and I don't think it is just because I am older.
Newer games that comes out in the past few years like Ultimate Marvel vs Capcom 3, Super Smash Bros Brawl / Smash Bros 4, Ultra Street Fighter 4, Mario Party 9 / 10, Final Fantasy XIII-2, ... all have fantastic fun factor with the increased graphical and multiplayer output.
It is a strange paradox about video games, how they seem more about business and competition, and less about overall fun factor.
I dunno about now but I had a snes and a ps1 in the nineties and they were both fantastic. Street fighter, final fantasy 7, the first metal gear I played. They were legandary. Am old smes. one called rock n roll racing was my favourite. That was back in 92 or something. We used to play that on four player till our hands stopped working
New PC all the way. I really wan't a ps4 though... The only ps I have ever had was ps1 :( . I have played some games on ps before and it was awesome. I have also tried Xbox but I have never been a fan to the controller. Wii is a family game, gets kinda boring playing alone. N64, only for Super Mario, Crash Bandicot and Spyro.
