Yes I do and I play it often among my best friends, they say it's too hard for them, but they don't mind it.
They key is to make a real true friends who will accept any and every non-hostile differences (except when you would be talking about Touhou all the time, being obnoxious)
So in other words, a person you can be yourself and feel comfortable around
- Without being irritating, because everyone hates it.
Playing and winning game requiring this much concentration is not something cringe worthy at all.Many people who haven't seen it will probably think that the character sketches quality is not the best (being polite) but then again ZUN starts everything around music first, doing a design along the line, maybe it's one of the reasons why countless people are re-arranging the brilliance of his original songs, into practically any genre you can think of.
Then again same goes for all the character designs too, as the main point is the story line and gameplay.
It's been proven that high dynamism in games increase your reflexes (not being a complete lard ass helps), and ability to make decisions faster. Some people like playing fast-paced FPS, others like platform game type of fast.
You can't make people like something forcefully, it's like I would shove broccoli in your mouth every day, even if you are big fan of it.
What you can do tho is (1). subtly just do what you do around them, and if they feel interested, they will probably ask you. Just try to be natural as if it's your hobby or one of these things to kill time. If they ask you why these characters look so ''cartooney'' just answer that the creator is from Japan and that's how animated characters in their culture are generally designed, just like the western cartoons are more smooth-lined caricature-like drawings for most part.
And for most part, think what you say, don't be stiff, unless you like when someone is hard as a sweat soaked dildo towards you.
And think about most important thing, find other hobbies than Touhou, because just as much you want others to share your favorite franchise, just as much they would like to speak about something that they are into with you, so they'd be participating in a dialogue, not listening to academics about Touhou by mr Autismo,
And since you are the one who wants to make friends, you should put effort into learning more about their hobbies.
(here we come back to ''(1)'' , when now they are Sprite and you are the thirst.
