Things I love about this game so far:

1.  Never ending!
2.  Ability to create more than one company
3.  Ability to have a parent company with unlimited subsidiaries
4.  Ability to merge companies
5.  Graphical map
6.  Ability to adjust the initial capital going into a company.

3 - This would allow an experienced player to get a company started and then sell it to a new player.  Which is a great aspect to a never ending game.  This would ensure that experienced players wouldn’t get bored because there is always a way to make more money and at the same time help attract and retain new players.
