And what have the coders and designers been doing for the last six and a half years?
They weren't there. Steve has mentioned that at the start it was just him pretty much, and it's only been somewhat recently that he has a whole team.
Same thing happened with a game called Kenshi, was only one person working on it for several years, then he started getting a team, and after 12 fucking years finally released version 1.0. Main reason why it was so much faster to make that game is because it doesn't have a sandbox like WL does, nor does it have porn, nor as much interactivity as WL, nor as high quality graphics and everything as WL. So far, I've seen more from Steve and his team working on WL in the last few years than I did in the the whole time following Kenshi, and I've seen more work done on WL than most of the other porn games I tend to find on this site of nothing but people fucking complaining when a game is taking longer than they like or doesn't play as they want it to.
