Both SWOS and Frontier consumed an unhealthy amount of time for me - I think I went 4 months straight playing Frontier when it was released... I had millions of credits, the biggest ship possible, etc!
These days I use the cargo space cheat and keep my little ship... but mod it with 1000 shields etc!
SWOS was the same - playing match after match... One of my best friends at the time was amazing.. He could beat Man U with Darlington (or beat Brazil with the Faroe islands) getting into double figures for numbers of goals he scored! We never could figure out why his strikers continued to lose value though despite scoring hundreds of goals in a season!
