But things have dramatically changed and Valve has to be already thinking about implementing changes, the more companies cut out Russia (doesn't matter if it's purely a PR move), the worse Valve will look without any actions or statements. It's also not only about users, they have to better protect their business partners or at least give them better tools to protect themselves.
I hope you're right, but sadly, I don't think they will do anything.
It's their "thing", the hands-off approach. Plus, they clearly don't want to piss off their Russian and Chinese partners, with fear of being banned there, and the users doing this toxic campaign mostly come from these places.
Nowadays, Steam is quite an unpleasant, toxic place. It's true social media platforms are as well, but Steam's community tools are nowhere near as effective as the ones users have in social media platforms (to block content and interactions from certain users, filter/exclude words, ...), so you have to "put up" with a lot of crap if you check your updates/community feed, forums, or store page.
If it's in terms of sales, I kind of agree (although, I doubt they expected particularly big sales, shmups are a nice genre, especially titles selling at full price).
If it's in terms of the quality of the game, I highly disagree. The game is a blast. Pure arcade perfection, a marvellous "classic" (non-bullet hell) shmup, with plenty of cool game mechanics, various unlockables and modes, and an insane soundtrack by Yuzo Koshiro.
I know most people (outside of fans of the genre) don't see shmups as "worthy" of selling for 40€, and that is something I can understand (these are usually short games, that fans of the genre play for countless hours, but some are just interested in "finishing" it, and move on), although I'll never understand how then these same people are willing to pay more than that for a cosmetic on a "free to play" title, or how they are willing to buy 5/6/7 yearly season passes for a Ubisoft game, that grant you a couple of cosmetics, and not much more, but different folks, different strokes.
But, the game is well worth checking out, so hopefully it will reach a greater audience when it has a sale in the future.
