It's good but does not stack up to previous games. It seems to lack a sence of complexity. The original towns are tiny and there seems to be little to do outside of your house. But saying that, your house can be incredible with all the customisation options so why would you ever want to leave?
All in all, the towns could be bigger and could have more things to do outside of your own home but other than that it's great and you can sink many hours into it.
