Kingdom Hearts, Kingdom Hearts 2, Paper Mario, Star Wars: Kotor, Halo 1 and 3, and Mario & Luigi: Superstar Saga are the ones that did that to me. Either they were really long, rewarding games (Mario & Luigi), they had engaging stories (KH), or they just had a completely epic finale (the Halos).
Could I trouble you for some maple syrup to go with the plate of roffles you just served up?
