All i want to do is turn on my tv and play video games with a controler (no console) Is this possible?

Well. the difference between a game and a movie is that the movie is just a rote streaming file, and a game is actually a computer program. So a game requires branching instructions to be evaluated and executed, which is what a computer's core CPU does, and GPU to interpret the graphic coded instructions into a video source. Smart TV's obviously contain lots of graphic processing ability, connecivity solutions, so on,but not much code execution CPU Based logic ability. if there was a sufficient computer built into the tv, then yes, you could load in a game program from any storage source, like a disc, or a thumb drive and the built in computer could run the program, if the computer's operating system code was compatible. Small computer CPU's and single board computers are becoming cheaper and game consoles that have a TV screen built in have passed through the marketplace from time to time. They were unpopular because of the cost, and the fact that most people already have a front room TV, and felt no need to buy another just because it had a gameboy built into it. Not sure about remote controllers. Wireless mice are available, possibly aftermarket game controllers, you would have to look. I doubt, even were it made available  that people would want to pay the price for a whole computer on board the game  thumbdrive everytime they bought a  game cartridge though. A program, like a game, requires the computer to run and interpret it, which is what a console really is, a computer.

The Sega Genesis Classic Game Console with 81 Classic Games Built-in sounds like the perfect game for you! Here's a link to check it out.. https://bit.ly/36QEiW8

I think you are describing Stadia.

Hope you have good Internet bandwidth.

With your description, nothing like that exists, at least not that I'm aware of. Most smart TVs can only read compatible media files, and games usually aren't like that.

you're talking about video games.  that means there has to be processing power somewhere in there, a cpu of some kind

if you're talking about really simple games, or really old ones, you can get away with very little processing power- it could be contained in that controller maybe-

but for anything more than simple, or anything approaching the current "state of the art" where video games are concerned, you're going to to need a pretty substantial processor somewhere.  that's what your console is for

you could probably market a tv with a console built into it, and do it that way, but there's going to have to be one somewhere

i know there's one or two outfits trying to sell video games on a sort of "cloud computing" basis, where the game is hosted remotely, but what with the inevitably latency introduced by a network, i'm not sure that's ever going to work as well as having a substantial processor and storage right there with you
