If you could combine 2 games..

[Avida]

Katamari + COD4

..

*drools*

Also

I'd like to see the Crysis nano suited FPS style game with the storyline from Command & Conquer 3 (the Tiberium Wars) with you playing as one of the GDI Elite Commando units :-D

C&C Renegade was fun, but it wasn't everything it should have been :-(

Yeah.. basically getting made already [http://www.moddb.com/mods/command-crysis-the-dead-6]

I want to do more games but I'll stick to the rules.

Probably Oblivion with the Mount&Blade combat system.

If I was to add more together I'd take pieces of:

Oblivion - open fantasy world and depth of gameplay,
Thief - great thieving gameplay,
Mount&Blade - parts of combat system, especially mounted combat,
The Witcher - flashiness of the combat system and "realistic"/adult fantasy world and
Assassin's Creed - parkour, climbing and graphics.

I really think that would be my perfect game.

MGS4 + Saints Row 2
I have no idea how it would work, but I have occasional flashes of awesome going through my head...
Perhaps Saints Row with Snake's gadgets or something...

Portal and Half-life 2.After the Orange box having a portal gun just feels right.

I agree with this, and think it's probably the best thing to do with the portal gun. While Portal was an incredible game, it's also a very closed game, a simple stand alone narrative from start to finish. It doesn't need a sequel (or a prequel for that matter)

However, placing the Portal Gun in Episode 3 would be an excellent idea. Image fighting combine with the portal gun?!

left 4 dead and Dead rising, i just want either a left 4 dead campain in a mall, or improved controls and characters for dead rising.

How about Dead Space and fallout 3, Cuz I LOVE dismemberment combat, I love to shot somthings legs off and watch it crawl to get me and to watch a super mutant do that would be twice the joy.

Hmm, I'd probably pick Resident Evil and Soul Caliber.

Nothing would be cooler than seeing a licker be killed by Killik, or more funny than Ivy be zombified because the ugly witch wears nothing but a bikini chain-mail!
