I see your perspective, but I wouldn't call Vanillaware a "small time" studio/name by any means these days. The guys have been around for over 20 years now. They've made their mark on the industry already.
True true, but they're still small with like 30-40 employees and making relatively niche games. Its important to note that even if they don't get
as much coverage as medium or big studios, they still get
a lot more attention than other similarly sized niche studios making similar types of games.
For example, i mentioned ProjectMoon earlier. They have a similar size to Vanillaware and also make games that are very popular among certain niches (Its estimated one of their latest games is over 500k sales on steam alone). Lets compare how much reviews their games receive compared to a VW one.
13 Sentinels got covered by 70 news outlets for the ps4 version alone (there are 36 others for switch). Library of Ruina on the other hand got covered by whooping
1 news outlet on Xbox. It doesn't even have a PC page on Metacritic which is where majority of sales were.
My point is, Vanillaware for its size and type of games they make, get a lot more attention and are a lot less underrated than people tend to claim they are.
