Do you know WHAT you miss????????
1. You can host IDLE SERVERS(you can select how many days it's on, the idle server is on EVEN if your computer is turned off!)
2. You can select a 800*600 resolution(I wonder I can do it!) and ALL options without running JJ2!
3. 90 levels and 10 secret levels
4. You can join/start servers. It shows NAME / TYPE OF GAME / PLAYERS IN THE SERVER AND MAX PLAYERS LIMIT / PING
5. You can do EVERYTHING like you are running JJ2!
