Support discounted lands and buildings, unlimited mith sales, unlimited xtal usage, discounted xtal/nob packages and discounted seal/horn prices. Also support 50%-100% more gold from all EBs for 24 hours on Friday.
NOW...there is something you could do as far as the lands and buildings go.
At midnight EST, Have a ridiculous starting sale of like 90% off all lands and buildings. Do this for about an hour. 2 hours tops. Let players know ahead of time so they can't get butt hurt if they lose out. After the first 2 hours, drop the sale to 75% for about 6 hours. Then drop to 50% for another 6 hours and the rest of the day drop to 25% off. Coupling this with all day sales of xtal/nob/seal/horn packages and even double gold ebs, it would be one hell of a Black Friday.
You could do the same with all of the above mentioned things as well, but I figured buildings and lands would be the best example.
Speaking of Black Friday stuff, when are we going to know what will be expected?
