space invaders is retro.
metal gear solid is not. it is a "classic" game that does not fit into the retro game theme, part of the "modern" era of gaming and gameplay.
you could however, motivate it as a metal slug type character with metal gear influences.
just because a game is old and you can see the pixels, does not make it retro.
retro is a styling term, and in this case, retro games refer to games like mario, zelda, sonic etc. mythical and magical characters that do not fit in with the modern characters.
solid snake would not look out of place next to splinter cell, call of duty or battlefield. its classic, not retro.
although no one is going to stop you from making a metal gear texture, and if its good enough, it would still be posted separately in the showcase
not as part of the "lets create" event though.

Digital Art - Sonic the H!
Used: ArtRage 4.02 + tablet
Time: 35 min
Notes: Done like oil painting on canvas, on purpose,
to emphasize that 'retro' feel (like paintings they used for posters during that
period), but character is new one, stylish, like in today Sonic games...
Fuck-up: Note to self: Do not presume that 900x900 pixels with 600 dpi is
enough for quality render,
it is not enough. Next time, x2 size, lower dpi.
