Looks like a fun game, I don't really have enough time in the day to play games like these anymore ;-p

It is becoming apparent that a lot of new games now are using the freemium economic model to attract players. It makes sense since it is becoming a lot easier to create computer games with all the software tools available to use today, more game creators means more games and players only have a limited amount of time. So they are more likely to try the freemium games first.
