Good concept. But it needs work.
I like where the author is going with this, but it needs a lot of work. Real Estate definitely introduces a newer and more intellectual stat-builder sim than the mass-produced dating sims seen on a weekly basis. And it's one that actually works in context. Problem is that not all people on Newgrounds can understand the real estate biz. So a tutorial would not have been a bad idea. Questions like "what buildings should I buy?"; "how much maintainance should I perform?"; and "how much rent should I charge?" could be basic tutorial FAQs to be answered. Red bars do a good job of being general data, but if you really wanted to get in-depth about it, you could explain more about the house like realtors do in real estate ads. That definitely would've added some points to not only originality, but also creativity and style.
It's a good concept in its early stages. Hopefully you'll consider what I've said and make a version 1.1 later on. I'd love to see where this kind of things goes down the road.
