Hello! Welcome to the site! I hope you have a great time here. For enjoying reading, I would recommend a ton of games but to take less time the top rated page contains many good stories (if you're someone who doesn't trust links, which I understand, it's storygames on the left then top rated). If you want to read to help the authors as mentioned, on the home page (click home on the left or the bar at the top) there's a section that says top 5 storygames in need and every time you rate one it brings a new one.
This is for reading at rating the games, which is appreciated, but more helpful is reviews. A review is basically an in-depth comment on a story, and this has good suggestions for how to write a helpful review. Again, if you don't want to click the link its Help & Info on the left and almost all the way to the bottom.
Happy reading! :D
