Okay, i just finished the game on hard...
maybe it's just me, but HARD mode, while being fairly realistic, detracted from my experience when i had to frequently save to keep alive.
gonna beat it on medium and easy to get all the medals though. Gotta replay omaha with a little more flow.
I figured when i bought the game i definately had to play hard mode, because it's more realistic and woul take longer... but it was a piss off with the stops and starts, the sniper parts! and the "final run"... I feel good for finishing it without cheating, and managing to get that last medal was a bitch. whew...
