Loved Scorched Earth. Had this fun bug/feature related to the weapons market. Between rounds you used your earnings to buy more weapons for the next round. There was an option to make it a "free market" which meant that the prices would get jacked on the weapons that you bought most often. But - and I didn't know this at the time - the price of an item was represented as a signed int so if you jacked the price high enough (which didn't take long) the price would flip over to a very high magnitude negative number and they'd literally pay you to take the nukes/MIRVs/dirt-bombs/napalm off their hands. Good times.
