I mostly play old Asian games like Go and Riichi Mahjong, although I'll give anything a chance as long as it has cute girls in it.
I taught myself Japanese by playing Japanese porn games for hours everyday for years. I knew ten words for penis in the language before I knew how to say "you're welcome". It was a lot of fun, and also very disturbing. Learning Japanese like this is probably the most horrific way to learn a language short of going DIY and tying up a schoolgirl in your basement. I've seen shit that makes Kaiji look like Care Bears.
So, nowadays I like to play games that are fluffy, happy, and warm, in an attempt to build back up the parts of my soul I sold to speak moon. I've got nothing against grimdark, I've just seen enough of it to sate my appetite for the next couple decades or so.
