I find this intriguing. From what I've seen so far, you were pretty busy in the game design forum, not specific to someone's project. Unless it is either that is what you call "care", or you did it but in private, or I simply missed it.
If you mean "lately" (within the last few years, where my post history has basically tapered off to maybe a couple times a week, provided it's not an actual conversation I'm having), then you'd probably never see it.
I don't typically post in the "I'm advertising that I have a game, plz review" portions of the forums (Okay, I've never posted there), so it'd be easy to conclude that "I don't care about people's games".
I spend most of my time in the "Game Mechanics Design" and "General Discussion" sections of the forums because it's where people tend to ask questions about Game Design or Player Psychology. Which, generally means, these are people often reaching out for help or feedback on whatever it is they're doing.
The problem is simply that over the years, people have shifted from asking, "I want do thing, how I do thing and make fun?" into "What are your guys general opinions on this vague concept I'm shopping around?". So, there's not a lot of space to actually "show I care about your personal game" as I'm basically just answering over and over "This is what generally works and why" or "I personally like this for X, Y, and Z".
The other problem is that I've simply "muted" a lot of what I actually think on the forums and refrain from offering much criticism at all. Because, even when I'm not offering criticism and just making an observation, somehow people will find means to turn it into an argument or a fight. It's honestly just easier to not share my opinions to avoid dealing with fights.
I've picked up a few games here or there that are RPG Maker and "given them a try". A few are pretty good, a vast majority are "par for the course", and several have some major issues.
I just don't "overtly care" about people's projects because people tend to just wish I didn't have opinions. I mean, one need only look through the topics on "how to deal with criticism" to see how many users would rather start a fight with me using semantics than take the advice of "You really shouldn't take criticism personally, though you should learn how to parse it" seriously. With the amount of users who can't handle, "Maybe your critics have a point" on these forums, I feel no need to comment on people's games what-so-ever.
But, I do care that they do well. I do care that people complete their projects. And I am impressed by anyone who can and has released a game. After all, I might sit down and play it at some point while seeking ideas, fun, or just to pass the time. I care that I have a good time.
