For all its faults, MK vs. DCU is an oddly enjoyable distraction from "real" fighters. Its masher-friendly controls appeal to 1UP in a casual-gamer way, and the midmatch minigames (damage-percentage tugs-of-war, airborne ass-kickings with the defender mirroring the aggressor's button-presses in a bid for dominance) give the fights a sort of party-game vibe. Even the online mode is virtually lagless; outside of a parade of day-one savants.
1UP just wishes the game's signature (and somewhat watered-down -- go Teen rating!) Fatalities ("Heroic Brutalities" for the politically correct DC heroes) appeared in each character's move lists, as they would rather not look up a button combination every time they want to shoot their opponent in the face or drop a Mortal Kombat arcade cabinet on his head. You know, the important stuff.
