You sound like someone trying to eliminate competition for a scarce item by trying to convince others why it's a bad choice.

People like what they like for their own reasons. Trying to tell them they're wrong to like those things is a waste of time. Some will be like you and prefer the smalls because they like feeling confined in a small space. Others won't because they like large open spaces that can't be achieved with a small.

Smalls are only better in that they are easier to obtain due to lower price and larger supply. Players are going to go after the mediums and larges because of the additional flexibility that comes with them. You can turn a medium or large into a small sized space yet have 100-200 more items to place. Want an attic floor instead of a basement floor? You can do that with a medium or large. You can't with a small.

It's great that you find your small fits what you want. I'm sure there are other players who feel the same way but you're never going to convince the majority when the larger sized houses can give the best of both worlds.
