Shovel Knight.
Initially, there was a single campaign, now named Shovel of Hope.
Then came Plague of Shadows, allowing you to play an alternate story from the viewpoint of one of the game's bosses, with completely rewritten story, dialogue, and even some entirely new stage segments alongside the game poking fun at itself (the powerful Relics you'd find as Shovel Knight? Useless trinkets you trade away to the very merchant you buy these from in Shovel of Hope.)
Then came Specter of Torment, upgrading all owners of Shovel Knight to Treasure Trove including all three campaigns, local co-op, and - which I believe is a nice touch, as the lack of female combatants in the Order of No Quarter personally somewhat bugged me - a gender swapping mod, allowing you to pick a gender for each character.
Female Shovel Knight except that everyone assumes (and talk to her as if) she is male because of that ♥♥♥♥♥♥♥♥ helmet you never see come off? Sure. Body: Female, Text: Male. Done.
And now we're getting yet another campaign for King Knight, co-op for the other campaigns, a four-player battle mode - all for free!

And those who don't have it can buy Treasure Trove for 23 bucks. I mean come on, think of mainstream games like Call of Duty or something - 60, 70, 80 bucks for maybe 10 hours of gameplay?

I don't see why Yacht Club Games wouldn't be one of my favorite developers out there.
