The awards bit puzzles me. Were there really that many, if any, video game awards back in the 80s and early 90s? I know CES gave nods to games on show, and I am certain SEGA received recognition back then. But the Interactive Arts and Science Hall of Fame began in 1998, and stuff like televised video game awards and the British Academy Games Awards are products of the mid to late 2000s.
Really, the awards back then were sales and market share, which SEGA was strong in their glory days. That's all that really mattered then.
As for modern awards, SEGA has received a lot of E3 recognition and Alien: Isolation won awards in Europe. Also, the Smithsonian has Virtua Fighter in their collection and SEGA received a lot of recognition in that Art of Video Games exhibit.
