Don't think it's as rare as we all may think.
My best guess is that less than 5% of the library would qualify, so it may depend on your definition of rare, but to me that would be pretty rare when over 95% of yours games have some form of scoring.
I guess my example would be Crypts of Chaos and Strawberry Shortcake: Musical Match-ups.
Crypts of Chaos does have scoring, but Strawberry Shortcake is a good one, although it target younger children and has a pseudo timer in some variations with the sun.
Why no homebrew? Is it too common on the new games us modern developers are making?
I was just curious what games went against the grain during the original run of the VCS/2600.
So far, what I have is the following:
- 3-D Tic-Tac Toe
- Maze Craze
- Riddle of the Sphinx
- Strawberry Shortcake: Musical Match-Ups
- Swordquest Earthworld
- Swordquest Fireworld
- Swordquest Waterworld
- Video Checkers
- Video Chess
Let me know if you can think of any others, or if one of the above games does have a form of scoring.
