why no accounts?

Yeah, it won't stop hackers and whatnot (though it is an extra complication for them) but it would be a solution to impersonation, and could be used to track achievements and other things (which is another deterrent to cheaters).

Preventing players from cheating is important. Detecting when players cheat is possibly even more important. A common strategy is once cheaters are detected to let them keep playing for a few weeks. Then you drop the banhammer on thousands of players at once. From that point on players will hesitate before cheating because the player will never know if the dev knows.

Thousands!
