If we think about games in 3 types based on expected playtime, short (expect less than 20 hours or so), medium (roughly 20 to 40 hour), long (the "normal" full GOTM)... then if there is a 6 month or 12 month general plan (not the specific maps, but the general type), then for the "long" type (3 or 4 of these per year) can and really should have at least 2 months to submit. Not becuase it necessarily takes 2 months to complete, but so that a person's schedule (work, school, tests, travel, etc.) give a larger window of opportunity to actually play the game. It would be a shame if a person could play a September long (for example), but had the game time to do it a week after it had to be submitted. Better to just extend and advertise well in advance the submission window. And even better, is to ensure that a "long" can cover at least one "holiday" period. Some people have more time outside of holidays, some have more during holidays... but giving the option may allow more people to play. In any event, a "long" game should have more than a 1 month window . Its still a "Monthly" game, but some games take more months than others . Between "longs" can be "shorts" (OCC, probably) and "specials" (like scenarios, surprises, unusual challenges, etc.). Some more information/possible ideas are also in this thread, "GOTM with 10 Cities".
