I was musing in the Backlaugust thread that
Conker's Bad Fur Day has both very good single-player and multiplayer modes, and it got me wondering what else might fit in this category. Some others that come to mind:
Perfect Dark: a refined version of GoldenEye's single-player with tons of challenge and cheats, while the multi is so extensive I still can't think of a FPS that outdoes it with options and challenges. Rare knows how to cover all their bases.
Streets of Rage 4: Tons of difficulty options and rankings to shoot for in single, with an excellent endless mode for multi.
Pikmin 3: The challenge modes are great fun with a buddy and like all good ranking systems, keep medals separate between both single and multi-player.
Advance Wars (series): Dual Strike in particular comes to mind, but all of these excel greatly in multiplayer due to how tightly balanced the games are. Also, edit modes!
Anyway, what other games come to mind for you?
