I’d get something regardless of if it’s on Steam or not, but I do enjoy things being on Steam. It’s a nice way of storing and streamlining your games so you don’t need to have them spread across disks and various online retailers. Personally, I get most of my games digital nowadays, so the lack of a physical copy wouldn’t bother me (got one for Clannad anyways, though). People are especially inclined to try new games if they are on sale on Steam, even if some other online retailer might have the same sale.
I totally agree with @Aspirety in that Steam is the largest, most public market to appeal to. There’s not really anywhere else to target if visual novels truly want to get off the ground overseas. I think it’s great that we’ll have a chance of getting even more amazing visual novels coming to Steam and being seen by a wider audience.
Making posts on my phone is annoying. I feel like I keep talking in circles.
