Trainz is awful. I use the word in its meaning of "commanding reverential respect". (You guys over there, not Canada probably, would use "awesome" with no chance of being misunderstood but I that is too new a word for me). Just look at those little guys in the Trainz intro - they know.
Trainz is the only computer game or simulator I have ever tried, it works fine on my 5-year old computer that was never meant for games, and it is fantastic what it does for just £12.95.
Btw, I have had the glass drop out of big light bulbs leaving the cap behind in the light fitting and I did take it back to the shop.
