1. Friend Lists
- See what games they are playing, profiles, comments, instant messaging, etc...
2. Counting The Time Played On Games
- I love just counting how many hours I have wasted on games, and sometimes even limit myself to how much I play. It could maybe be optional to letting other people seeing your hours or something.
3. A "Recommended For You" Section
- Pretty self explanatory, just some part on the website that recommends some games to you depending on the ones you have played so far.
- Write your own reviews! Let other people know what games are your favorites! It's a good way to learn about other games you may never heard of before.
Feel free to add on.
EDIT: Some grammar mistakes yo.
