Horrible game.
Horrible post. Care to explain?
No freedom, early game enemies are hugely overpowered, no plot, you have to pay money at every turn to actually play the game, the list goes on.
Do you even try to check?
Airport missions have the following enemy cards:
Red cards, which contain very strong enemies.
Green cards, which contain quest enemies, which you use to extract dna from to finish.
Blue cards, which contain normal enemies fitting your level.
Item cards: Selling, or using on your creatures.
Power cards: For health, happyness, or stamina.
Money cards: Self-explanatory.
Not all enemies are overpowered, in fact, some enemies do more damage to certain creatures, or are more effective at something. Finding the right skills work out.
Do you mean by REAL money? You don't have to. You pay in two currencies, one which you collect from the game, another which you buy with real money. In fact, most things you'll be using requires game money, and now paid-for money.
You have some form of freedom basically. You can go mostly anywhere, but the stamina really pisses in the sink, when you have to keep chugging down drinks or wait for it to replenish.
Is there anything else you'd like to add up into your list?
