I am trying to come up with a system to measure or estimate the skill of a player at a single player game (so no head-to-head rating system help here). Specifically, it is a pinball game, but I do believe it is similar to most point-based single player games.
I have thought of 3 approaches:
- total points scored with a threshold for each skill level
- average points scored over all time
- average points scored over last X games
All of them use points, which I think is probably the right metric: anything a player does in pinball grant points, with the most difficult objectives worth more points. Points also take into account all of the rare combination of objectives (like score multiplier + multiball) that would be hard to track manually.
However, I am not sure which approach to use and I bet other games have implemented similar skill-measuring system that I can use as a guide, so I'd appreciate any and all help on this.
