if you install it from the openSUSE repos, using YaST or Zypper it
will automatically be added to your menu…
see, it sounds like you are using that oh-so-last-century way of
installing new applications (the Redmond way: go somewhere, download
something, click click click…) don’t do that because you don’t know
who out there you can trust…
stick to the repos until you are more familiar with it…
I just installed etracer on my 64-bit machine using zypper and there is no entry in the kickoff menu for this game. You can add it to the games section by right clicking on the kickoff icon and selecting menu editor.
You can also type etracer into the search field of the kickoff menu and launch the game from there.
