It was discussed a while ago regarding combining chess variants. Fencer said it would be extrememly simple to add combination variants with the way the system is currently set up. However, where does it stop?
Dark Gothic, Loop Gothic, Extinction Gothic, 3-checks Gothic, Dark Janus, Loop Janus, Extinction Janus, 3-checks Janus, Dark Loop Gothic, Dark Loop Janus, Dark loop, Dark 3-checks Gothic, Dark 3-checks Janus, Dark 3-checks, Dark Extinction, Dark Extinction Gothic, Dark Extinction Janus, and on, and on, and on...Not only would it be very difficult to distinguish these games (aside from the name at the top - not a big problem), but it would simply be WAY too many games and would be almost identical.
