fun idea
 

I was talking to some people on dustari today, and i think it would be very interesting to have weather. Like very bright days, foggy, drizzle, and heavy rain or snow...It would make things more realistic.

Already suggested a lot, but still a good idea.

Night and daytime, weather with effects like fog, mug (slower) etc - it'd make GK much more realistic, I agree, and atmospheric, you should even be able to catch a cold of you forget, say, a raincoat during rainfalls - but it would require severe scripting, and people shouldn't be able to switch it off to get an advantage... I'd appreciate such additions anytime though ;)

That would make the spells daytime, night, light, darkness, summon fog and night vision do something :)

Funny idea, a player running arround with a spot of sunshine arround hime... or even better, a rain-curse - bright suneshine arround except for the one single cloud hovering above the poor cursed person... Also, I think some resistance-effects would be nice, like resistance to fear and death lowering during the night or something...
