If a DRM measure doesn't stop a game from being pirated, then how is it going to improve sales?
Say you have 10 people. 5 are legit and 5 are pirates.
If you release a game with no/minimal DRM, 5 will pirate it and 5 will buy it.
If you release a game with crazy DRM, 5 will pirate it and 4 will buy it and 1 person will ponder whether to pirate it or not play it at all.
