Maybe, but it's only free on windows, on Epic Games' store, which has a monthly free game apparently. They seem to be trying to buy their way into the user count steam has, and it might even be working.
This was driven by the seemingly "easy" profits from the GTAV Online marketplace, and also why Grand Theft Auto V has also gone free, with bi-yearly "big crimes" that players can buy into.
Same is true of XCOM, which they also own and has been releasing yearly DLC for.
I find this sort of thing a bit short-sighted because although I loved all three of these games, I still get bored of the same mechanics and would rather dive into something new.
If they're putting DLC deployment ahead of fresh IP development (which they seem to be), then I guess that's why I sold my TTWO shares yesterday.
But for god's sake, take the Hulu approach.
Both Origin and Uplay were a hot mess last time I tried them, when if they'd cooperated they would have had the resources to surpass Steam. Short term thinking at its finest.
