They’re otome, but they’re also non-hentai, so there’s no worry about seeing something that you don’t wanna see.
I’m told that Asaki is very good, and a rough English review can be found here. On 2chan the music and artwork were highly praised, as well as possessing a complex plot that requires seeing all the scenario to fully grasp what’s going on (this was stated in a positive manner). Someone told me that I didn’t have to like otome games, so long as I was open to the idea of playing a female lead seeking out a boy… and honestly that’s not a big deal to me, seeing how I’ve played female leads in extreme eroge quite a lot: Gun-Katana and EXTRAVAGANZA for example . In the least, it has a beautiful OP song and sequence. I’ve seriously considered playing it… just haven’t found any time in doing so.
However Souten is not seen in a positive light. At best the comments I’ve seen for it are often “average” and “not what I was hoping for” - so I’d think it’s best to pass that one.
