Tower Defense Games
Everything is decided before the wave starts. After that you just watch whether you were right.

Tower defense is the only genre where the interesting part of the game happens while nothing is moving.
How this list is put together
You place towers, you spend what you have, and then a wave walks in and resolves the argument. Everything that decides the outcome was settled before the first enemy appeared — which position covers two corners of the path, whether you bought range or damage, whether you saved for the expensive tower or bought three cheap ones. Once the wave starts, you are mostly an audience for your own planning.
That structure makes failure unusually informative. Losing a wave does not mean you reacted too slowly, it means a specific decision three minutes ago was wrong, and you almost always know which one. That is why people restart these instead of quitting them.
What separates a good one from a long one is whether the towers force a choice. If everything dies to more of the same tower, you are only clicking. The good ones give each wave an armour type, a speed or a flight path that makes one of your options useless, so the money is spent on judgement rather than repetition. The maze variants go furthest: there the towers are also the walls, so you are not just choosing what to build but how long a walk to force.
Questions people ask
What makes a tower defense game good rather than just long?
Whether your towers force a choice. If every enemy dies to more of the same tower, you are only clicking; the good ones give the wave an armour type or a speed that makes one of your options wrong.
Do I need to keep playing during a wave?
In the strict ones, no — the wave resolves itself and you find out whether your layout worked. That is the appeal: the decisions all happened before it started.
What is maze defence?
A variant where your towers are also the walls, so where you place them decides the path the enemies walk. It turns the game from choosing what to build into choosing how long a route you can force them to take.
