Cool Combination of 2 Games

[rockingnic]

Assassin's Creed + Ninja Gaiden
Halo: CE + Halo 3
FF11 (jobs and create-a-character) + any RPG

For me, probably Hitman and Prince of Persia (best elements of both series). Sort of like Assassin's Creed but better. I'm hoping that number 2 lives up to expectations so this will be rendered unnecessary.

 

[Booze Zombie]

Team Fortress 4 Dead.

Theif 2 + Assassin's Creed - repetition = awesome parkour system with fantastic stealth and amazing open world gameplay

Even better!...Well, almost.

mirrors edge+ =awsome
Actually, left 4 dead with mirrors edge flow and call of duty quality ion sites. Anyone ready to start deving?

 

[Whoolpurse]

Zombies and MMORPG's

 

[Yegargeburble]

My personal vision is a mix of Fallout 3 and L4D. Open world, zombie co-op fun.

If it is possible to mix in some of Assassin's Creed's free-running, then so be it.

 

[Mirroga]

Assassin's Creed + a Thief game. Assassin's Creed world and gameplay would be awesome if stealth was ever implemented.

 

[riskroWe]

Counterstrike: Source and Bioshock.
CSS needs customisation and atmosphere, Bioshock needs fast-paced team-based competitive multiplayer.
And not just plasmids, I wanna play as splicers too!

 

[Meado]

Mass Effect + Star Trek
Technically cheating, but it would be awesome.

 

[Mrsoupcup]

Battlefield: Bad Company and Mirror's Edge.

Holly crap thats exactly what i thought! Runing through a building under artilary fire is hard core man.

Pokemon and WoW

or

CoD4/CS/TF2 and WoW to make some crazy online game.
