Quoted from EaglePin:
I think it comes down to AIQ not having enough emotion or those big pinball moments in games when you know you just did something big.
Yeah, this is it, there's no big moments. Winning a gem should yell out a huge "GEM VICTORY!" fanfare. Instead what you get is a "final blow" display for two seconds that you can easily miss, and a confusing aftermath where you still have to make two more shots to collect and place the gem.
The big moments aren't emotional, they're all mathematical. The big moments are when you set up a big Soul Gem jackpot or shield bonus or Binary hurryup or combo jackpot, with some combination of powered-up avengers and gem placements. That's what the depth of the game is about, and what the game is designed to be doing... but it's really obtuse and tangential compared to what the main progression of the gems should be. Winning a gem should be the big accomplishment to celebrate, not just one step out of five more convoluted sequences to make it do something useful. Each gem should do something big *right when you get it*, not just modify stuff for later.
Quoted from TheLaw:
I personally don't get the "no energy" thing at all, but the stacking being confusing I find myself. There's always a countdown going on I have no idea what it is. Probably using the characters voice should be telling me but it's still like; "Whatever."
Those countdowns are either one of the Super modes started from the computer grid, or the timer for a tower super jackpot during Iron Man multiball. Neither is really important for gameplay (although super modes can earn a trophy), they're just a few million points. There are no countdowns for the gem quests, even though that's what anyone would immediately assume it is. The countdowns have nothing to do with which character is speaking, that's just random.
