That's the thing. And you will possibly never get it. To you it's a game. Just a game.
Firstly Trainz isn't a 'game' on any level. There is no scores, no winner, no loser. It's a sim. There's a difference.
And to most serious content creators and route-builders it's not even 'just a sim'. It's an all-consuming passion. You don't get routes like mine or Fred's or George's or Joe's from folks who think it's 'just a game'. You don't get trees like Trunda's or Pofig's or Jan's or Dave's from folks who think it's 'just a game'. You don't get locos like Justin's from folks who think it's 'just a game', or skins like Mick's or Mike's. You don't get hundreds of crossings to choose from because Clem thinks it's 'just a game'.
To all of those folks Trainz is somewhere between a very very serious hobby and an all-consuming passion, and I suspect for most of those I've mentioned - and there are hundreds of others - they are way up the 'passion' end of the scale and the stuff they produce takes pretty much every minute they can spare for it.
Then somebody comes along and slaps a cruddy skin on a loco or completely mangles a route or whatever and believes they have a RIGHT to upload it, distribute it, call it 'mine', use it as they wish because it's 'just a game' and 'not worth getting worked up about'.
Wrong. Dead wrong.
Go play your 'game'. I'll stick with my passion for the best sim on the market and I'll stick with the folks who have the passion to create some of the best freeware content available anywhere, for anything.
But my content is mine - not yours....
