So, I had just worried myself just for nothing??? ☠☠☠
Well it's not like Touhou is going to explode or anything. There's still a lot of Touhou content on the horizon.
I will never understand why touhou mobile games always *have* to be gacha of all things, though
There's a few decent Touhou mobile games that are out there (Shout-out to Suika Combination, Mawaru Marisa, Thousand Night Anamnesis and 東方おはじきパズル). The main problem is that Gacha games are the most profitable ones. Games like Super Mario Run have proved that people aren't interested in priced mobile games and sadly most big mobile developers do depend on whales in order to keep themselves afloat. But just like many of the Moriya Shrine OP's points, it's less of a Touhou problem and more of a problem with the game development environment of mobile games. I don't see it as "We are making a gacha game because it's the trendy thing to do" and more like "This is the only formula that can assure us good sales". It takes a lot of money to pay for the artists, VAs and all those composers they have. But as long as they don't get greedy about it, I'm okay with it, it's not like I'm going to play them anyway (No matter how good looking the swimsuit Kogasa illustration is, I won't go back to LostWord).
I have to admit, I personally wouldn't mind seeing Touhou have a bit more commercialisation. Yes it might "ruin" the doujin spirit in some way but it would mean more accessibility of Touhou content to the West. We got Touhou on Steam, maybe just maybe we could even have officially translated Touhou manga being sold outside of Japan or even just more Touhou merch overall but at this point I pretty much sound like a hopeless romantic.
