A: PS2, SNES, OG xbox
B: PS1, N64, Gamecube, Sega Saturn, NES, PS3
F: Xbox 360
Only rated consoles with finished lifespans + PC.
S is PC for obvious reasons. A are some great consoles with great games. B are some good consoles too, but worse than A. F is reserved for the only console to break on me twice and become redundant outside of a few games.
