This really should put each system with it's corresponding generation of consoles.
Sega Genesis was way cooler than the Super Nintendo. Sorry, but for the 16bit systems, the Sega wins out.
My history of video game systems through the different generations
8 bit: Nintendo
16 bit: Sega Genesis
32 bit and 64 bit: PlayStation
128 bit: PS2
Xbox 360
EDIT - The SNES was a 16 bit console, but IMO had way better games.
I had both a Sega and the SNES and in games that were multi platform like Madden, NBA Live and Mortal Kombat the SNES was superior in every way, plus Mario > Sonic. Then there is Donkey Kong, Mario Kart, Super Mario All Stars, TMNT Turtles in time.
So here u go
-8 bit - NES
-16 bit - SNES, see above.
-32 bit - PS1 - another game changer, the discs were so intriging, when I was at my Uncles house one Xmas and saw him play Madden on the ps1 I was completely blown away. My dad had gotten me a Neo Geo or maybe a TGX 16, and when he saw the ps1 played, took me right to Toys r Us the next day, traded in the Neo Geo and games and bought the ps1, I think we played it all night.
-64 bit - N64, in a league of it own, it was the PS1's only competition and was better in every way, games, controller, memory cards, don't agree just look on eBay, you can find most ps1 games for less then $5, while Mario Kart 64, Goldeneye, Mario 64 and Zelda are going for $200-$300.
-128 bit - Xbox, I had a ps2 and was a ps fanboy, but when Xbox made the smaller controller, then brought all the GTA games over to Xbox, I switched, the Xbox was a better system, loading times were faster, graphics were better, and then there is Halo, which changed gaming forever and for the good.
-Last gen - Xbox 360, Xbox Live, buying games digitally and the largest library of games of any system ever, now the PS3 had better specs, but the online was a ghost town and the only exclusive worth playing was Uncharted.
-This gen - I have the ps4 and the xb1 and like I stated earlier the xb1 is my gaming device and my ps4 is my blu ray player. The ps4 like the PS3 may have better specs, but not by much and nothing that really catches the eye. My reason for playing Xbox is the social aspect, I can get on my Xbox at any time and have 30-40 friends on, playing a variety of games, so if you like MP games, I have someone to play with all the time. While PS has done better, their online service is still buggy and broken, share hardly ever works and when I go to a lobby, most people don't even have a mic, and I mean in COD or BF, where on Xbox and PC, everyone has a mic, making multiplayer much more enjoyable.
Sorry for the long post, but never say that the Genesis is better than the SNES, like comparing Volkwagon to BMW.
