Team Fortress 2 x Minecraft.
Come on. You know it would be epic. Rather than single matches, the game is a huge MMO-ish game set in the Minecraft world with more of a TF2y look, where you have to work with your team to carve out a fortress of your own, which is destroyable via the various wepons. Imagine, going Spy, C&Ding until night-time and luring Creepers into the enemy base. The ores could be crafted into various crafting metal, and it would still keep TF2's random drop system.
Godamnit, someone needs to make a TF2 weapon pack for MC.

Other crossovers I've thought about include but are not limited to:

Ace Attorney/Resident Evil: Umbrella Corporation is being taken to court over recent apparent neglegence in the company relating to the safety of its employees, but there's more to this than meets the eye. Can Miles Edgeworth uncover the truth and expose Umbrella's dark secret? (Wesker needs to be in this. Are you a bad enough dude to cross-examine Wesker's testimony?)

Elite Beat Agents/Space Channel 5: This probably doesn't need any explanation. Fuck knows what the story would be.

Layton/Silent Hill: The more intelligent a person is, the more likely they are to be completely fucking nuts. Science says so.

Street Fighter/Silent Hill: There were game mechanics and everything for this one, but it was basically sticking El Fuerte in some horrible nightmarish place full of dirtied, dull neon skeletons and bollocks like that. Still need to draw him covered in blood and dirt and holding a steel pipe. Shit was epic.

In fact, Everything/Silent Hill. Crossing Silent Hill with anything instantly makes it awesome. Prove me wrong.

TF2 / Minecraft sounds good to me.
TF2 / Megaman - they could replace or battle their appropriate counterpart robot masters (say Heavy would be Hardman, Demoman would be Bombman, etc).
Layton / Eversion - "This block reminds me of a puz--OH GOD WHY IS THE SCENERY MELTING?!"
Anything / Amnesia. Fucking lol.
Anything / Moonbase Alpha - UBRBRBRBRBRBRBRBRBRBR.
Recettear / DooM - yeah I've no fucking clue.

Phoenix Wright/Harvey Birdman. Just because.

Monster Hunter / Left4Dead= Dear god, fighting Rathalos WHILE a horde of zombies try to kill you with just a catlike humanoid on your side? This sounds so crazy, it´s good AGAIN!

Silent Hill/TF2= How Dr Tanner already said, everything SH crossovered is pretty AMAZING.
And now imaginate a Silent Hill Story with one of your favcharacter of TF2. Yeah, pretty cool, wouldn´t it be? (Oh good i can´t unsee Medic called Kaufmann.)

TF2 / Destroy all Humans! = Happens to be in the Timeperiod? Check. Socialhumor? Check. Weapons who can bring a good laugh out you? Check. THIS i want really to play.

A TF2 fighting game (or at least TF2 chars converted to Mugen for the hell of it) would be pretty sweet.

Left 4 Dead/Zombies ate My Neighbors: How cool would it be to fight off infected and horror movie monsters. Also, Zoey looks a lot Like Julie (the female her of ZAMN)

Kirby/NiGHTS into Dreams: The style of both game series and the fact Kirby lives in a place Called Dreamland also helps.

Psychonauts/EarthBound: Psychic powers galore!

Jet Set Radio/TF2
The idea of heavy grinding a comically undersized rail makes me giggle on the inside.

And then I realized how dirty that sounds.

Oh God, why didn't I discover this thread until now? My brain LOVES churning out weird crossovers when I'm least expecting it.

Ace Attorney/TF2: "Objection! The autopsy report states that Mr. Heavy was stabbed with a short, straight blade! That does not match the description of the Kukri used by the defendant!"

Psychonauts/TF2: Perry and I once actually came up with rather complex designs for Psychonauts levels based on the different classes' brains.

Pokémon/TF2: "SNIPER used JARATE! Enemy SPYs defense greatly fell! Enemy SPYs cloak was cancelled!"

Warhammer/Advance Wars: I actually wrote some rules for Warhammer Characters based on AW COs. Olaf was a dwarf, Adder was a Dark Elf, and so on.

Warhammer/TF2: I can totally picture Solly as an Orc, Engie as a dwarf or Spy as a Dark Elf.

Psychonauts/Watchmen: Well, Watchmen's not actually a game, but I find the idea of running around the inside of Doc Manhattan's or Rorschach's brain creepily, mindfuck-inducingly fascinating.

EBA/The Lost Vikings: The protagonists of both games frequently travel through space and time, so crossovers would sorta make sense, in-universe. And Olaf the Stout in a suit would be hilarious. Especially if he's doing the YMCA dance.

L4D/Pokémon: Blastoise, Charizard, Tyranitar and Alakazam (or any four awesome Pokémon of you choice, really) against hordes of infected Rattata would be all kinds of awesome.

Super Smash Bros./Henry Hatsworth: Not so much a crossover, more the fact that Henry needs to be a playable character in Smash Bros. He has a bunch of different moves and weapons, his game is on a Nintendo console, and he's hilariously british. What more could you ask for?

Evil Genius/TF2: Just....I can not describe it

Snipers are all like Minions, Scout's mother as Alexis, Engineer is Maximilian, soldier is soldier, heavy is mercenary/Freak, Spy is John Steele...
Too many things in my head.

There's a lot less crossing over of it than I thought. Like, a little drawfaggotry, one porn pic, and a video or two on Youtube. But I could totally see Medic going batshit on the other team with a foul mouth and wrecking shit up.

Oh hey, I made that. And drew one fanart.

Robin Atkin Downes voice acts both, and they're both psychopaths, so why not?

Never posted here, but my best bro linked me to this. Yeah. We got some good ideas.

Silent Hill + Persona: Main Character's Persona is Pyramid Head, he has a lot of undertones of sexual repression. Entire game has sexual undertones actually. Mannequins make much spotlight in the game and stress on MC.

Lost Planet: Extreme Conditions + Morrowind: Remember Scribs? The little try-to-be-cute insect like things that would startle you awake when you were sleeping out in the field? I bet you don't remember taking them on when they were 17 feet tall in a mecha of Dwemer origin.

Shadow of the Colossus + Any football game: The Colossus are the football teams. Debating whether or not you can be a Colossus on the team, or if you're still Wander against the other teams. Horse optional.

Monster Hunter + Garry's Mod: Lol.

Operation: Flashpoint + Dragon Age: This is probably DnD, or Modern DnD. But it does have a certain charm about it....

Half Life (2) + BioShock: Honestly, I would love to see Gordon Freeman have to take on a Big Daddy with a Crowbar. Or Alyx and Dog dodging cross-fire-fights with Little Sister/Big Daddys and Combine Soldiers. Setting would probably be funnest to explore in HL levels.

>Operation: Flashpoint + Dragon Age

So like Mount & Blade but with a Warhammer: Fantasy Roleplay level of lethality?
