Two very different games, one identical price: zero.
The two very different games are the current freebies on offer over at the Epic Game Store, which you can sign up to with a secondary email/VPN if you really, really don't want to hand over your actual data.
Your mileage with the games might vary wildly. Metro 2033: Redux is the best and perhaps most condensed version of 4A Games' survival-shooter series, although I've still got a soft spot for Metro Exodus. Everything, on the other hand, is one of those games that hugely divisive. You either love it, or you find it annoyingly obnoxious, as Amanda did when she played it at launch.
Before the debacle around the Epic Games Store, the Metro franchise had established a reputation as a deep, hardcore survival shooter with a focus on story that was increasingly lacking from the modern video game landscape. What's fascinating is that's primarily how the Metro franchise established itself in the first place - by going in a different direction from the norm.
I went into David O Reilly’s new game having seen nothing aside from a few screenshots. I wanted to be surprised, and was prepared to be, if not blown away, at least challenged by its unconventionality. What I got was a first year theatre student gurgling warm milk for half an hour.
Either way, you won't have to pay a cent for either game. You'll obviously need an Epic account, or have authenticated via something else (like your Xbox or Switch), but you can sort all of that out here.
