I'm pretty happy with how this area ended up. I've had a few compliments on the design and thought I'd toot my own trumpet by posting it here too. My process of 'construction' is that I start with an idea, so in this case I thought "Factory theme" and build a ride. After the first ride is built I'll plan a footpath and the general guesstimations of the other ride/shop placements. Long story short, nothing but the ride placements are predefined and I just build scenery around them until they meet up with other rides scenery. It's what's worked so far, so why fix what ain't broken eh?
