I know for Id Games (RTCW) you could install the game, pack the installation directory into a self-extracting executable, and extract that during your unattended installation. Possibly you could capture the Add/Remove programs entry for RTCW from the registry and include that too. This in case you might want to update the game in the future. This method will work for a lot of games. If it complains about dll's it cannot find (in the windows directory), find out which and include those in your self extracting executable. FarCry, for example, writes 5 dll's to the Windows\System32 directory. Good luck, eNuffSaid
