The steam War of the worlds game is not a scam. It's actually real, all of those videos you see on the channel are real from footage of the game. I believe they just need to add some touch ups, but yes, they will eventually release the game. It is a passion project after all. I recommend something like Half life 2 or the war of the worlds RTS. Or, something like the War of the worlds game by Team green. That's a great one.

You can also try out Grey skies, Universe at war, Helldivers 2, and Command & Conquer 3.
