You could also use a separate prefix for each game - the disk space
overheads aren't all that big. This way you can permanently add the
registry entry permanently for the programs that use it and not for
those it harms. As an added bonus you'll no longer run the risk of
screwing one game up while patching/upgrading another.

IMO with separate prefixes its easiest to use a wrapper script to run
each app/game. The script sets the correct prefix, changes to the
appropriate directory, runs the app and exist. You make the script
executable and have the app's menu entry run the script rather than
running the app directly - the latter assumes that all apps are in the
default .wine prefix..
