So far, I've been owning
1> Atari 2600, Amstrad CPC 464 (some kind of shitty computer with ultra hard games on audio tapes... Shit like this: https://www.youtube.com/watch?v=ZgufriFkri4 )
2> Genesis, Game Boy
3>Saturn and Playstation
4>PC
5>PS2, Xbox, GBA
6>3DS
I'm only playing PC and 3DS now, I might buy a PS4 for FFVII remake and GGXrd though.
So long, i regret not owning a neo geo, but hey, shit is expensive. too bad the Saturn crash big, there was a lot of fun game on it (Mr Bones, Dynamite Deka and Guardian heroes for exemple was pretty neat... And I like the version of Doom). Happy i didn't pay for this piece of shit 32X though, I wanted it for Doom, not knowing that it's one of the worst version ever.
Mostly, I've played so much games I regret nothing. I've played most games I've ever wished to play trough emulation or friends, so it's cool. And now, I have so much shit to play on steam... I'm really happy I have all this good time through gaming.
Maybe one regret : I never own Sonic 3, so I havenever beat Sonic3&Knucles without emulation. But hey, the 5th emerald was so hard to get, i might have fail anyway :)
