A game you could play every 2 or 3 months

Wind Waker is a good bet. Possibly Dark Souls (and/or 2) and Xenoblade, those are a little too new to know for sure. I could probably play Mario 64/Sunshine/Galaxy/2 every few months.

Ooh, Kid Icarus: Uprising. Yeah, I think I could do that.

Then there are really short games like Portal and Journey that seem like no-brainers just because I could finish them in a single session.

Honestly, I could probably play most Zelda games every few months. LTTP, Ocarina, Link's Awakening, the Oracles, Minish Cap, Wind Waker, probably even Skyward Sword and Twilight Princess. As before, LBW is a bit too new to be sure.
