Let's be honest - there are tons of games with amazing-unique-marvelous-etc renders, but there's only a few games that present players with a real "story", and CI is one of such games (because instead of a usual cheap porn-plot it presents players with a psychological drama about two broken people). If this game was a text-only, it still would've been amazing.So what you are saying is the dev should release a 'dialogue only' update, but i'd assume people only play this game for the amazing render quality and we will still be waiting over a year for each update.
And so, gonna fix it for you -
Since patreon rewards include wallpapers in 10$+ tiers, and author makes ~1200$+ per month with ~140 patrons, it's safe to say that majority of them are mostly there for these wallpapers he makes.but i'd assume people only pay for this game for the amazing render quality
