Yeah, yeah, we're all great at being cheerleaders and groupies for our games and the designers who made them, but there's nothing perfect in this world. Let's hear one thing from each of the games that you own that you consider to be a flaw. No copout answers either where your criticism is actually a veiled compliment or bookended between praise. Just give an honest bit of criticism. I'll start.
Spider-Man - The art is bad. Also, for a game that flows so quickly, there are a LOT of stops. Yes, you can double flipper to skip, but even then the ball rests a lot.
Attack From Mars - The Attack Mars mode should have included other shots. It's just a hit the middle over and over deal. It would be cool to have to hit a ramp or loop between middle shots to "reload" your missile launcher or something.
Creature From the Black Lagoon - The hologram window can cause some unfair drains as it changes the ball momentum. Obviously, the hologram itself is also terribly problematic.
The Bride of Pinbot - Lack of modes make it a "shoot the left ramp" game unless you're committed to maxing out your score without a billion point chance. Most won't play that way, however.
Tron - The recognizer target blocking the Gem shot is a bummer. Too bad that there wasn't a bit more space here to allow for an unobstructed shot at Gem, because after dropping the disc once, it can get harder and harder to collect Gem shots as the game goes on.
AC/DC - The canon should always be controllable. I like randomness in games, but drains from it random firing is a step too far and it's annoying.
Twilight Zone - Shooting the skill shot is an invitation to drain without ever touching the ball due to the crazy dangerous pops. It's a shame you can't get a safe plunge when you hit the skill shot.
The Addams Family - Most of the modes can be outright ignored and getting to Tour the Mansion is a fairly safe endeavor. Very few risky shots, aside from bricked chair attempts.
OXO - The tic tac toe stuff is cool in concept, but too random in practice which is a real downer.
DE Simpsons - There's no real modes, it's just a get multiball and shoot the left ramp sort of game. Unlike BoP, you really need to just keep hitting that left ramp at all times.
The Simpsons Pinball Party - A lot of the really fun modes are hidden behind a lot of work. Most casual players will never see the best that the machine has to offer. The garage door is also somewhat problematic and when it only opens halfway, it's a real annoyance.
