Pay off any debt/bils or anything my parents have and buy a nice but not large house with a lot of land, build the best possible gaming computer with the current stuff. Then invest a good portion of the remainder in stocks and stuff.
Actually, assuming it would be enough, I would buy out this little place near me call Foxmoor plaza(or whatever it is called, the name changes often) that has been going through new ownership every couple of years and turn it into a family compound complete with nice stone walls surrounding it. Then I would move my enitre family into it, cousins and all, and rename the place to something involving Morro, my last name. Then my family would be an influential land owning family of the area. Also, invest what's left so that I could replenish the money.
