OpenTTD (Transport Tycoon) - Too Adictive!
Running a computer games club at the college I'm at, I was looking at free games, open games, or anything that didnt cost money. So the students could play together nicly (yes, I know Im hopeful)
Anyways, I ran across this little gem, something I remember from years ago, its "Transport Tycoon".
It appears some nice people have managed to recreate most of it as open source, its even better than the original and its simply fantastic!!! The many hours I lost on the original I appear to be losing again now.
Who else remembers this little wonder, and who will now be addicted!
