...I loved the old Sierra games
Railroad Tycoon
Takedown Wrestling
Centurion Defender of Rome
Theme Park
Battle of Britain
So many of those games had so many cheap flaws that unintentionally ended up being great cheats. On Railroad Tycoon you could keep building Powerplants with money you didn't have and you'd send the company into so much debt that it turned black as in you literally had the cash, on Theme Park when you negotiated with unions you'd budge a little bit on a wage increase and then drag your negotiation back and have the unions eventually accept a decrease in pay and in Battle of Britain you'd pick a German bomber, go do a bombing mission, but instead of going to Britain, start turning back and hit the gunners window to gun down anyone and everyone, parachute halfway back across the English Channel and get a massive score and an official medal of honour, and in Indianapolis 500 from memory you could make your car invincible, turn around and destroy the others in head on crashes and then go around and win the race.
Either way, those games were all rippers, and a lot of them were good ones to compare and compete against my brother.
