I want to play titanfall on 32 bit

But why though? I am using a gaming laptop that can play the most graphically and processor melting games made today, Including Fallout 3 and NV with full 4k High def textures on basically everything, thousands of modded quests/weapons/armor/animation /scripting events, precise hit boxes to a tee (even upon mass explosions), an ENB realism visual subengine executable, etc. Which in total is 4 times more demanding than titanfall, and all of this on a windows x84 (32 bit) operating system. So why, was it just a heat of the oment choice, or is it the devs thought the average gamers' pc could not register it with the lower ram and different code paths associated with 32 bit? Just curious since I bought the game not knowing it was 64 bit only, and am debating whether to return it or do the time consuming task of "upgrading" my pc to 64 bit.
