it's better to do a GOTQ (quarter of a year)
(my experience from the christmas time/ early 2006 GOTQ)
maybe best a Game of the (Half) Year.
that's more realistic ... most people have very little time,
the old timers (... ~30 up to ~50...) will just play
when they have some kind of timeout
(sickness, at home vacation, 3 rainy days in a line etc.)
...?
it's not good to FORCE people by setting to narrow limits,
let's give the freedom to play/compete over long distances...
... the game is 15 years old, we have (had) time anyway ...
for example
the
The SPACE RACE CONTEST: Go For ALPHA CENTAURi
is perfect as it is (even with it's bugs)
so it may run forever...
