Ruin a game with just one letter

Bar Game : Red Dragon. Do you dare take that redhead home from this dodgy and badly lit watering hole?

I immediately thought of this

Farts of Iron IV: Waking the Tiger

Hearts Or Iron: Loving the Tiger

No Man’s Spy

Has Dart Souls, a game about people who care quite a lot about little throwing arrows been done already?

Not according to the search!

Pith of Exile

No oranges for you!

Garframe: space fish play free

Winecraft: get drunk on blocky stuff.

Dongs of Conquest
Bongs of Conquest
Tongs of Conquest

Poop Hero was graphically addicting. I played it once a day at least.

Company of Herpes

Diaplo: Immortal

(explanation: this game is so dispicable, any letter can ruin it, or no letter at all, it is already ruined)

God of Car

Ahaha genius!

Bar game : red dragon. Do you dare return that red heads’ flirtation?

Diablo Immoral.

Amazon is apparently asking folks if they are looking for

Fire Emblem: Three Holes

I opened this thread substituting herpes for heroes, but I guess it counts.

How about a deckbuilder rpg about terrible fonts? I give you:

Midnight Sans
