do you think a system is worth keeping for 1 game

Depends on the game, and how much you love the game. I bought the N64 for one game. For almost a year, Super Mario was all I had for the Nes. Street Fighter was all some gamers ever needed for the Snes. And Tetris Attack is the only Snes game my mom has.

long answer short: yes.
