2) Game Boy (1989)
The Game Boy took full-fledged cartridge gaming portable and, even though it had a green-and-grey screen, it handily trounced the colour-screened Game Gear and Lynx. Why? Simplicity. Solid battery life. Affordability.
And yes, Tetris. The pack-in puzzler was the ultimate time-killer and paired perfectly with the portable - and who can forget Pokémon Red and Blue or Super Mario Land 2? The enhanced Game Boy Color helped bridge the gap until the brand new Game Boy Advance, but the original model forever changed how – and where – we play games.
1) Super Nintendo (1992)
The two systems below this one might have been more innovative and crucially important to gaming, but, if forced to pick any one game console to bring on a desert island with its entire library of games, we'd be hard-pressed to turn down the SNES.
Bumping up to 16 bits unleashed the creativity of developers, taking decent and so-so 8-bit genres and elevating them to greatness, and the Super Nintendo has an all-time-amazing lineup of games. The Legend of Zelda: A Link to the Past, Super Mario World, Super Metroid, and Final Fantasy VI are just the tip of the iceberg. This was Nintendo – and some traditionalists would argue, gaming on the whole – at its peak.
