This is not guaranteed to actually find a matching plugin for a gameid. A good example there this fails is platforms, which use engine plugins. One could have game entries in the config file, for which the engine plugin (is no longer) installed. Thus plugin would be 0 and gameInfo would be an "empty" game descriptor.
