How do I download a game onto a flash drive on a MacBook Air?

[kaylabug82]

My Memory is only 4 GB 1600 MHz DDR3 and I can't download a game because it needs 10 GB. Also can I play it with just the stick in my computer by opening the file? I don't know much about this kind of stuff..Thanks

that 4GB is the RAM, that 10GB is disk space needed. Not the same thing.
