As much as I love Batman66, Elvira has a lot more variety as of today. Plus it still has things yet to be coded into the game.
For multiballs Batman66 has 6; villain, villain escape, Holy, batusi, and gas attack.
For multiballs Elvira has abouy twice as many at 13: wild women, zombie attack, attic attack, trunk, phone a friend, gappa angry, pool party, dance fever, make-out mayhem, scream test, run for your life, house party, directors cut.
For toys/mechs Batman66 has; the awesome center rotisserie with 3 sides to it (2 sides are stand up targets and 3rd side has physical ball lock and center pass through shot), penguin crane, penguin VUK, riddler saucer, joker magnet, gadget 6 target stand up bank, TV 3 target stand up bank, villain vision mini LCD, 3 pops, spinner
Elvira beats Batman66 here as well with; awesome house toy (has multiple diverters and locks within) with impressive color changing lighting effects, spinning turret on top of house with 4 positions, house ramp that allows shot into house or lifts upfor shot under house into celler, drop target in front of house garage shot, back door scoop behind house, dead head crypt with 3 positions that all register hits (closed, open into scoop, open into bash toy), crypt VUK shoots ball across playfield to hit trunk targets via action button, trunk that opens closes as part of left ramp to locks balls, 4 jumping gargoyles that hit the glass, manos virtual spinning wheel, 3 target stand up bank for Trunk, 3 target stand up bank for manos, 3 pops, spinner
Things to do for Batman66 involve fightging 4 main villains (2 episodes per villain) or 1 or 6 minor villains (some minor villains have multiple seasons some just 1 season), bat turn side mode, villain escape multiball after capturing 4 main villains, choice of multiball after played 1 minor villain for each of 3 seasons.
Elvira beats Batman66 again for sheer number of different things to do; house has 6 main haunts and 2 or 3 hidden haunts (requires key from trunk to unlock), 3 multiballs on the garage shot, un-happy hour mode, drive me car-azy mode, capture items from the trunk(dagger, potion, key, ray gun) for extra game features, gargoils gone wild mode, gappa angry multiball (has 5 consolation multiballs if you dont make it to 6 on gappa), phone a fiend multiball via trunk, 15 dead heads to fight at the crypt, super dead head shot after beating 3 dead heads, manos wheel for awards, house party after 2 haunts, directors cut after 4 haunts, trailer trash after each haunt.
I think Lyman learned a lot regarding integrating existing video clips into game play from Batman and took it to the next level.with Elvira.
Batman66 shots are a little clunky while Elvira shots are smoother than velveeta.
I still love my Batman66 but I think Elvira just has a much wider variety of stuff to do.
