In the Binding of Isaac, you have 10 challenges on the main menu that radically change the way the game is played with small changes. These offer a reward of some sort when you finish them and people tend to spend quite a bit of time trying to master them.
So I think there should be a board you can interact with in town, containing a list of unlocked challenges you can choose to undertake for more more experienced players.
Examples:
Labyrinth - # of rooms on every floor is doubled and the minimap shows nothing. EXP, drops, score and gold are halved to compensate for this. Rewards: Beat the first 2 floors to unlock a 'Pyrite Shield' perk that makes all defended attacks break your shield, but increases score gain by 10%. Optionally, an actual 1 HP shield that has the same effect. Beat the first 4 floors to obtain a map item for your house.
Boss Rush - A full blitz through every boss in the arcade mode in a row with no healing inbetween, only gaining levels from the bossfights themselves. Rewards: Kill the first 2 bosses to unlock a sword bush in your town. Next 2, a shield bush. Complete the entire boss rush for +1 Maximum Perk Slots.
Antimagic - MP does not regen passively, nor does it regen between rooms, refilling only when transitioning between floors. Persistent magical effects like summons or shadowclone vanish between rooms, requiring them to be resummoned. Every skill or spell used is a precious resource. Beat floor 4 to unlock 'Energy Pack' perk, which adds +25-50? MP. Beat floor 8 to unlock 'Arcane Blade' perk, which refills your Energy meter by a % of weapon damage dealt.
Roulette - Every level up assigns a skillpoint into a random skill, with no more manual placement. Beat floor 8 to unlock 'Skillpoint' perk, starting you off with 1 bronze skillpoint.
