8. Psychonauts
Released in 2005 for X-Box, Playstation 2, and PC by Majesco, Psychonauts is the extravagantly well crafted game about Raz, a boy running away from the circus to become a psychic warrior. Created by Tim Schafer, Psychonauts is one of the world’s most entertaining games. Supporting characters are rich and hilarious, as Raz delves into their subconscious to save the day at a psychedelic psychic training camp.

7. Phoenix Wright: Ace Attorney
Developer: Capcom. Publisher: Capcom. Year Published: October 11, 2005. Platform: NintendoDS.
Phoenix Wright invents crazy situations, silly characters, and also definatly gives you a ton of laughes. It also is a great investigation game, that leaves you waiting for a sequel. And in each series, they bring you new characters, and more oddball situations.

6. Time Gentlemen, Please!
Dan Marshall and Ben Ward,
Zombie Cow Studios, 2009 (Windows)
Check out our complete review of Time Gentleman Please!
A new graphic adventure game, full of foul-mouthed juvenile student humour. It is big, and it is clever, with time-travel, alternate universe Hitlers, armies of cloned dinosaurs and plenty of sick jokes.
5. Fable 2
Developer: Lionhead Studios. Publisher: Microsoft Game Studios. Year Published: October 21, 2008. Platform: XBox360. http://www.lionhead.com/News.aspx?newsid=74
This game has you cracking up from the start! Everything from the People of Albion, the documents and item descriptions, to the loading menus packs some silly. The developers really hit the nail on the head. The comedy in this game not only makes you laugh, but it absorbs you into the world of Albion, making the game more rich, and fun.
Graphics can impress you, gameplay can engage you, but a joke or a funny situation is there to amuse you, and to help you connect to a character. Nothing cures a bad mood better then laughter, well maybe killing zombies, but to each his own.

4. Portal: The Cake is a Lie
The cleverest AI (GLaDOS) in video game history made this 2007 Valve Corporation release for PC, XBox 360, XBox Live Arcade and PS3 arguably the funniest game to be produced in years. GLaDOS leads us through cutting, darkly mind twisting blind leaps through puzzles, rewarding the player with pure entertainment. http://orange.half-life2.com/portal.html
3. Hitch-Hiker’s Guide to the Galaxy
Douglas Adams and Steve Meretsky, Infocom, 1984 (PC)
Immortalized by the tortuous puzzle to get the Babel Fish, this text adventure based on the cult radio series of the late 1970s is still developing a quarter century after its release, as the 20th anniversary Flash edition on the BBC website demonstrated. Featuring some exclusive Douglas Adams material, as well as a devious game engine that lies to you about exits, this was the first truly funny game I ever played.
2. Brutal Legend
XBox 360, other
Double Fine Productions 2009, http://www.gamefaqs.com/console/xbox360/data/943672.html
With the voice work of Tim Curry and Jack Black, Brutal Legend is the story of a hero who is vaulted back to the Age of Metal in order to fulfill quests and slaughter foes with the power of Rock. Considering that you can literally melt enemies’ faces off with your guitar solos, Brutal Legend blatantly aims to be a righteous send-up of metal rock humor.

1. Conker’s Bad Fur Day
Nintendo 64
Rare 2001, http://www.gamefaqs.com/console/n64/data/196973.html
Legendary for managing to cram so much adult humor onto a Nintendo game, this is not the mild-mannered Conker we know from prior experience. The game featured urination, swearing, and other crass features that were best left for its target audience of frat boys. Once the Mighty Poo boss shows up, you know Conker is a riot.
