Best value pack with 3 amazing tables + an X-men table.
Thor: One of the prettiest tables in the game, some of the missions can be hard to complete, although there's rarely a time limit on them. It's a bit imbalanced to one side, because there's object on the center-left part of the table, which might block the path of the ball as you're shooting with the left flipper, especially when aiming for center ramp. Those same objects are where you're supposed to acquire multipliers, so you'll be using the right flipper a lot. Overall a very fun table though.
Ghost Rider: One of the best tables in the game, now unfortunately slightly broken in Pinball FX due to new physics. The ball is now impossible to catch in Lucifer's challenge, however there's still a choice to play that with ball-save for smaller score wager, so it's fine. However, stunt combos are now much easier to do. In fact I'd go as far as call them unmissable. Otherwise the table has really good music and the mechanics are thematically fitting a Ghost Rider table, who is a stunt-man, so you gotta do stunt-combos on loop-de-loop ramps and warp-ramp combos. Because of those ramps the ball could slip out from the rails all over the place, but it's much less common, so the new physics are both a blessing and a curse. You can choose your mission every time and they're all duels against one of Ghost Rider's opponents in a stunt match.
Moon Knight: A table with a very finely crafted flow. Has a wide variety of missions, some easy, some boring, some interesting, and some videomodes. The final one is a bit hard, needs precise shots. There is one interesting mission where you have to trade stocks, buying low and selling high, in order to make a profit before time runs out. You can buy upgrades for your hideout (better scoring lanes on the table), there's shooting gallery minigame, a boxing minigame in videomode and a very basic minitable on the moon. Most mission have interesting narratives, but personally I always disliked it when the table is yapping too much. Visually it's a very entertaining table, although some of the art makes it difficult to see clearly what is playfield and what isn't.
Xmen: Weakest table in this pack imo. Gameplaywise it's kinda like William's Mars Attack with those risky center targets, although here the flippers are a lot closer together so catching the ball is easier. However, the table's flow is horribly messed up. There's a lot of shots that require the 2 top flippers, but both are place at high-speed orbits. Worse yet, Magneto will accelerate the ball's speed on the orbits and send it supersonic which makes top flipper shots straight up impossible. Pretty sure this isn't intended to work like this with the new FX physics. During some missions a pathway opens which redirects one of the ramps to the left top flipper, which gives you an easy shot, but that in itself requires the right top flipper which gets no setup. You're basically juggling the ball around trying to hit posts in weird angles to set the ball up for the top flippers, it's really not fun.
