Why should I lecture anyone here on what they find weird? It is totally up to you.
I'm at liberty to have an opinion on the matter though, given that this is a disucssion forum, something people here tend to forget the moment somebody actually replies to their posts...

I'll still hold my position that Japan's weirdness is highly overrated though, and is mainly due to ingrained euro/american attitudes which makes most people unable to see the weirdness in their own countries.

Statistically speaking though, these kinds of titles are of little to no relevance to your average Japanese person.
Even when a game sells really well(Dragon quest, FF etc), and hits 10 million marks etc, it is still only a small minority of the Japanese total population.
However games like these do not even sell really well by ordinairy standard. Similarly, they're aimed at a certain market, which consist of people who buy all these kinds of games.

The dog btw, looks like Hachiko. Whether I knew this or not, you should know Irony, is completely irrelevant to this issue.
