Games like Left 4 Dead

REFINE

These picks come from one game. Yours can come from ten.

A pack is 1 to 10 reference games you pick yourself, from your Steam library or the full catalogue. Two or three are already enough to change the question: instead of "a game like this one", we look for what your picks have in common, so the genre you're after comes through and the flukes drop out. We tell you how well your selection holds together, and you adjust and re-run as often as you like.
