"One update per year." Dude, we are talking about devs who do not work on this "full time." You can't expect loads of content when a dev barely makes less than 200 dollars per month... I really don't understand your mentality. You want badik levels of content with small devs who are starving.
I don't get it, these developers do it in their free time so they work in their normal day to day job, at least a bunch of them do. Saying that they starving because of it is just BS and you blowing this out of proportion more than it needs to be. No one says pirating or playing the games and bitching without supporting is a good thing. I already said I personally don't condone it, but you going a bit overboard here in your statement.
I reiterate. FACT: No one likes waiting a year or more for a game update, less so if you supporting the developer, but that does not change the fact that you allowed to voice your opinion on an open platform, stating what you think, as long as you doing it respectfully and without being a total dick, then I would say its fine.
FACT: A developer who can solely sits and builds VNs or other games to make a living would be probably having a hard time making decent money, but I would imagine has more time to churn out content than those working full time. So it kinda stands to reason to support the dude who is slogging at the game with no other income, but least you should be getting decent and probably regular updates.
Nway, my just my 2c. I have loads of respect for developers doing this stuff, building a story and telling it well, plus the added visuals, its a bit of work and you need to be creative. If you can support a developer that you can appreciate their work for, then do it.
