k first mkdir (make directory from terminal), or you can do it via the gui, where ever you wanna install the game(probably under your home directory. then cd (change directory) to that directory. with the file in that directory,at the terminal type tar zxvf filename.tar.gz and press enter, this will extract all the files. then ls to see what sub-directory everything was extracted to. then cd to the new directory, next type ./configure , then when that is done, type make, this builds your makefiles, then type sudo make install, this installs the program.
this guide works for any app you need to compile
if you get a file that has a tar.bz2 extension use the tar command tar jxvf filename.tar.bz2

hope this help...post back if something didnt work
