I can't play games??

WinRAR does support .7z format. At least the latest version does.

It's a shareware app, but it can be easily cracked. We won't say how, this forum doesn't support such activities.

WinRAR doesn't even need to be cracked. It's fully functional if you don't register, there's just a small nag when you start it.
