Maybe I'll think of an entry later later. In the meantime here's something I made which seems fitting for the thread.

Shouldn't it be "Watering Mars"?

Adding extra letters takes more effort, so Weeing it is ;)

Mars could be a lush paradise - all it needs is a little irrigation.

1) Prince of Popping [Prince of Persia] (Don't forget there's the DOS game, too :))
2) F*ckmagedon [Carmageddon)
3) C*ntima [Ultima]

Not that good or original, I know, but I gotta go to sleep :P

Kind of reminds me of that "Basso's Gamble" trailer that was released for that awful Thief reboot.

I was bored, so thought I would add a few...someone already took my, "I have no Ass..."

Quest for the Glory Hole (Quest for Glory)
Guilty Rear - Double the Load (Guilty Gear X2 Reload)

A new one, but oh well.
Eve the Whore - Mistress of the Broken Condom (Eador Master of the Broken World)

Ass of Wonders (Age of Wonders)
Gabriel's Night: Sins of the Mothers (Gabriel Knight: Sins of the Fathers)
Forgotten Reams: Demon Boneing (Forgotten Realms: Demon Stone)

Edited to comply with the three entry limit.

This thread is fantastic, +1 for everyone lol.

Okay! Let's see:

Dungeon Keeper - Whips and Chains Edition [Dungeon Keeper Gold]
Prickateer 2: The Dickening [Privateer 2: The Darkening]
Stagrunner [Stargunner]

Nude Raider (Tomb Raider)
Broken Sword III: The Sleeping Dragon (no change required...)
Urban Bugger (Urban Runner)

Hah, this looks fun.

The Dick (The Dig)
Another Whore (Another World)
Slutopia (Startopia)

Lol, I've been having fun reading the entries so far! Thanks for the giveaway, Charon121. I'm in +1

Dungeon Screamer [Dungeon Keeper]
Seize Her 3 [Caesar 3]

Redhead Action [Red Faction]
Star Whores: Nights of the Old Pubic [Star Wars: Knights of the Old Republic]
Master of Oral [Master of Orion]
Not a title, but in Carmageddon you can get a "stunning cunt" bonus [cunning stunt].[/i]

Wanking Mars
Alan Wanker: American Wet Dream
Balls of Steel (needs no changes :))

Heh that last one reminds me of that old, obscure, arcade game - Space Bugger

I'm pretty sure they didn't mean anything rude, just one of those 'lost in translation' things, which only makes it funnier IMO!

Commander Cream: Wet Dreams (Commander Keen: Keen Dreams)
Jackoff (Jackal)
Sid Meier's Colonization (didn't even need to alter the title to make it sound bad)

Wanking Wars
