Yeah, honestly I totally agree OP. I know there's all kinds of indie games, but what you're describing does seem to be a fairly dominant and long lasting trend in this area. Personally, nostalgia just doesn't work on me very much, and I as well feel like, been there done that with this style of game and it's just not what I want anymore and hasn't been for many years. But, there's clearly a market for it, so I just shrug and move on.
