I vote Alone in the Dark. It's super easy to platinum, doesn't take as long as FO3 or bioshock. It's a bit glitchy, and the story isn't as good as the other two... but (if you trade games) it'd be better to finish it now and trade it off, opposed to holding onto it and letting the value drop.
If you don't trade games, I'd still play it first because it's the shortest, and baring the glitches, the least frustrating in terms of difficulty.
*the glitches are annoying, but if you save often you'll be fine.
