As a point of contention, Drug Wars was popular back before even the TI-83 (not TI-83+) came out. My sister had it on her TI-82, and I had it on my TI-83, both long before the TI-83+ was ever released. Would be interested to find out who made the "original" version of the program, when they made it, and if the 82 was actually the first model they made it for, or if even that was an updated release...

Edit: as a btw, there has been a "drug wars" game available on the Android market for at least 3 or 4 months; long enough that I played it to the point of "beating" it and got bored.
