tbh im against buying into Early Access most of the time AVN's are the exception because the price is usually low and if I lose out on $10-15 bucks o well whatever. Something like this game I can replay once in awhile even if it ever did become a dead project cause what is there is very good and enjoyable for replays once in a blue moon.
Similarly, I support only 2 VNs full time (as in, Patreon going for years), 2-3 other subs that I normally swap from time to time. Just to give a bit to devs I like.
But when it comes to proper Video games, I bought 0 early access games (technically I had 1, Bannerlords, but I digress). No way. They are less likely to be fully released one day than VNs are. Especially survival crafting games...
TNT is only VN I ever got on Steam. What we got so far is amazing, Ceolag provides constant updates on progress, and even were it to stop (please no), no regrets.
Content gives so far, both game wise and discussion wise, makes me not sorry for spending a bit on it.
