That is pretty ridiculous. The block button is pretty valuable and important in MK, and just because it's different from other FGs doesn't mean it's bad. Lack of zoning? I'm guessing they haven't played any of the top tiers. Perhaps they should have got someone who is actually experienced in fighting games to review the game.
is the game only being sold to fighting game experts? Do you have to show some type of ID at the counter?
