Back in the day, and by back in the day I mean 4th generation video game consoles (SNES, Genesis, and if you're good with video game history, the turbografx 16 and Neo Geo) this would be pretty up in the air. Even then I would probably side with Nintendo but I would probably prefer the Genesis on a whole. Sega does what NintenDon't after all.Absolutely random question time!!!!
Which is better? Nintendo or Sega.
Otherwise, the Sega Master System was meh, the Saturn terrible, the Dreamcast awesome but too short lived.
RIght now, Sega is producing some decent/okay games and many crap games. So right now... Nintendo.
Nintendo is a hardware producer, and has first party/second party IPs including:
Animal Crossing, Custon Robo, Donkey Kong, F-Zero, Fire Emblem, Golden Sun, Kid Icarus, Kirby, Zelda, Mario, Metroid, Mother, Star Fox, Smash Bros, Batallion/Advance Wars, Yoshi.
In comparison, Sega is only a software producer and has... Sonic, Phantasy Star, Super Monkey Ball etc... (and a lot more, but few have had recent releases, and even those that do aren't very notable).
