Windows 95 thru XP are your basic workstation desktops. They were made for the person that just wants to use a computer for email, games, surfing the net. MS has tried to make these operating systems as idiot proof as possible.
MS also makes server operating system starting with NT thru whatever is now the latest and greatest.
Linux started out as server based operating system. Thru the years people have written desktops, games, graphical browsers, ... and posted them on the net for anybody to try, use or improve.
My answers to your questions:
1) Linux is not easier that Windows. It is more powerful and flexible. The Power and flexibility also by nature make it more complicated.
2)Freecell works just fine on Linux.
3) See answer to question 1.
Anything else: If you just want to play games stay with windows. But if your bored and want try Linux then learn to google, get a distro, oh heck just look at that link of Emerson's
