4) Additional Info, such as traffic details, revenue, cost of upkeep: There are very little visitors lately, due to lack of interest from me(i've basically let the site die). It would'nt take much to get it going again.. a little advertisting. The DB includes an email list so you could start there...

Both games are coded in PHP with some Javascript thrown in every once in a while.
These games come as a package, and I believe are worth more than $100. But, since you are buying a COPY of the game, $100 is fair. This means many people may buy the game, and change it to what they see fit.
