A Fictional question. (Imagination needed)

Imagine:
There will be a law that every game need to be mixed* with an other game…

Which game would you choose for Halo 4 (and: newer Halo-Games)?

→ I don’t ask this (only :p) for fun; it would be realy intressting what ppl say, because it would show some “directions” and “characters” of the different Halo-Fans.

[* with ‘mixed’ I mean: to move stuff from one game to an other (=exchange): like the Halo 4 Warthog in Forza Motorsport 4; but in much bigger dimensions…]

Halo + Pokemon

/sarcasm

I would like to see something spartan armor like in the fallout universe and vice versa

Special Brotherhood of Steel MJOLNIR armor

And imagine a spartan with a plasma caster! Plasma caster (Fallout: New Vegas) | Fallout Wiki | Fandom

I have two answers:

a funny and a (more) serious one:

The serious one:

NOT with Call of Duty
…but may be with Wing Commander (you know the old Space Fighting Simulator):
→ It would be ideal for space combat (much better than in Reach); arm and choose your own ship for a new UNSC-Space Mission. Would be awesome.
Also the Kilrathi (or whatever the WC badguys were called) would fit into the covernant forces.

The funny one:

With Forza 4 and Assassins Creed:
then you have an Assassin-Spartan-IV that is driving an upgraded Hennessey Venom GT (and a Smart ForTwo) … O.K. that’s only my dream lol.
… don’t want to reveal any more shocking details of my mind atm :D.

Halo + Star wars republic commando.

what odst should have been like in my opinion (don’t kill me I still like ODST anyway!)

Call Of Duty and ODST. I would have loved ODST to have ADS and a more ‘human’ health system.

EDIT: better idea, Battlefield 3 and ODST. ADS and a health bar.
