Okay, so me and SK often make "what if" scenarios, and I thought this one was good enough to share:

This is kind of a play of the "if you could only have so many games, what would they be" but going a bit more detailed.

Firstly, pick your three favorite consoles. Also, there is no such thing as backwards compatability (PCs and handhelds count as consoles). Then pick only one title for each console you chose. Seeing as most the time when people pick a "if I can only have such and such game, it would be these" it usually is on the same platform.

OR

List all the consoles you own or have owned and the one title you'd want to keep for each.
