Should be fine to buy one if you're just casual gamer and needs something to play once in a while without breaking the bank. People downplay the 360 saying it's old gen. But at the same time, it still gets new games once in a while. For instance, PES18 & FIFA18. Last I saw even FIFA19 will be available for the 360. That has to count for something right.

Used ones are really cheap now and almost always comes with games. But might as well get a jtag / rgh unit. I still use my rgh nowadays even though I got a one s already. Reasons should be obvious.

Unless you're a hardcore gamer that must have the latest everything, no harm really.
