Can an out side cumputer join a LAN game at my house?

Depends on the bandwidth requirement for it, but typically yes.  Set up an incoming VPN connection on your XP machine for him to connect to your lan with.

I have set up the VPN  connection, now how does the other computer contact mine. Do I have th provide my IP Address? And where would I find it ,  thanks

Where do I find the WAN IP Address

Im working on this now, how do I forward the port?

It is done through your router configuration page.  What router do you have?

Linksys BEFSR41

THen you should be able to go to the advanced menu, and in the virtual servers tab you can forward your port.

OK did that, getting error when trying to connect, where is the PPTP Passthru check box?

What error are you getting.

I went to linksys web site and they gave me some direction. I forwarded the ports, and they sai to set an IP Adress not automatic. I have not been able to test with an outside computer yet. I will keep you posted.  Thanks for the help.
