i am using Linux Lite 3.6 64Bit, i am looking for some games

[supergamer]

The problem is going to be 3d drivers for a lot of the games. The 16.04 base does not have the hardware stack for good working 3d. The fglrx driver will not work with this xorg version which means you will have to update to a newer mesa driver stack from a ppa then it only has limited support for older amd/ati graphics. Please read for more information.
