I don't know how old you are, but I get it: You're totally excited to be a programmer and really, really excited to be working in an up and coming language. That's awesome! It's a killer skill you have and you're on the cutting edge. But you really need to be less antagonistic about the way you evangelize your excitement.
I love love love the idea of H5, but I work in Flash because the install base is enormous, it's ridiculously easy to prototype and a portal like Kongregate.com can get a (popular) game upwards of a million hits. In contrast, my buddies who work at an app studio were over the moon that they moved 400k units.
We all understand why H5 is a "better" platform- It's open, it's accessible, it's native to the browser. And in 10 years it might well be THE dev language. I hope so! In the meantime, try and understand why Flash is still a serious going concern and why someone might use it. When you start chattering about H5, try and provide some examples other than ITS BETTER DUH.
As for "play", you're right. There's not a lot to "do" in Plinko. But there's also not a lot to "do" in Slots and they rake in billions of dollars a year- We, as a species, are wired for an attraction to random elements. We get an especially wonderful dopamine boost from unexpected rewards. Something like a slot machine or a Pachinko game make us feel good because we get to 'quest' for a pattern (Of which there is none) and we get a healthy boost of feel good chemicals when we 'win'. Point being: Even if there is less to "do" in a random game of chance, on aggregate you're likely to have a better time.
It's also a lot of work to get the physics right. When I release mine, take a peek: My physics are a wacky mess. There's a particularly hilarious bug where the puck gets stuck oscillating between moving left and right at 24 frames a second. Which is to say that there's a lot more to it than "if (puck hits peg) REBOUND".
Back to the point: I'm sure you're super smart and I'm glad you're a brave dude leading the way with H5, just learn to be a little less. Agressive?
