I agree with you in general, but in the case of Den: The Forgotten you had gameplay footage and multiple screenshots to view before making your decision.

99% of the games on here are garbage

You’re not wrong, but the 1% is why I keep coming back. I like the fact that the lack of barriers allows anyone to try their hand at publishing a title, and once in a while something genuinely good emerges that might not have come about on another platform.

The reality is that 99% of basically any form of media is garbage, you just usually don’t see it because of barriers that prevent people from sharing or major platforms using algorithms designed to only show you what’s most popular. I like that there’s a place on the internet where I can turn up a big rock and see what gremlins come out.

Sorry to hear about your frustration. But you should know game development is very difficult. 

It is very hard to be motivated, creative, and put in all the effort required to produce a full game.

I can't speak for any game you might have played, but try to realize testing is by itself tricky.

Quality Control and Standards can slip without the developer even realizing.

Most people a developer would know are infact not very reliable. These days it's actually a fight just to get people to test a game free or not.

So even for free games others will have to "pay" the "cost" post-launch by running into issues such as bad performance or bugs.

You never know why a game is priced the way it is either. 

When you see a game that is priced too cheaply or has a big discount, it might be because the developer has panicked and is desperate for players.

Don't think cheap means good deal on a good game. It all depends.

Looks are often deceiving btw. 

You must TRY OUT to FIND OUT. That's just the way it is.

You are right, you sound like a complete asshole.

You have other store with game filter, like gog, If itcho were the only online game store, I would find you right, but with other alternatives, I don't see the point of complaining.

Why you need to complain about itch don't have any type of barrier?

Here you find games or programs from people who participate in JAM, people who make their first game or create something totally different that will not fit in a commercial store and just want to share it. Complaining about all that, just because you have a game that you don't liked. To me, you sound like a spoiled child having a tantrum.
