How to implement the construction of player development levels?

Question

Game development

Hello!
Now I'm making a game.
What is the best way to make a player development rating scale?
Dependence of accumulated points and level.

Answer 1

In my opinion, in games, the number of points that you need to score for the next level goes exponentially. The higher the level, the more points you need to score for the next one. The rapid growth of the exhibitor is covered by the growth of points that are given for the completed task.

Answer 2

The first option - the number of points for each next level grows in arithmetic or geometric progression, the number of points received depends only on the complexity of the task / level of enemies.
The second option - for each level you need the same number of points, the number of points received depends on the ratio of the player's level and the complexity of the task / level of enemies.
In any case, the game should not allow a situation where the player gets stuck in any location due to the fact that opponents and tasks have ended, and the level is not enough to move on.

Answer 3

There is also an option using achievements (tasks / quests), the number of completed is an estimate for the rating. You can make the rating system dependent (achievements can only be completed after completing the previous ones, you can even make an achievement tree so that the player can choose what exactly to do)
