It's an online game like Hattrick and Itsagoal. Maybe it isn't as famous as those to but it only exists for 1 year and has a great potential.
The concept is like IAG: 1 game a day, during the week: 4 league games and 1 cup game. The persons who don't like HT because it takes so long, sure have to try this. In max. 2 seasons (1 season = 9 weeks) your player is maxed and you can compete with the teams from the top-divisions.
Also is reaching the highest division not as difficult as IAG where you have to pass over 100 divisions. On SP you only have to make it from F to A (piramid-structure, beneath every division are 3 others: A=1, B=3, C=9, ...)
This season ends within 1 week and then a G-division will be implemented, so it's a real strong sign that it's growing. (over 5000 players in less than 1 year)
