Gamplay Preview 1 & 2 Complete Breakdown
The devs showed us a bit of how the gameplay will look like and after watching thru it, I have some mixed feelings.
First off, the game might be 50gb or possibly even 60gb in size. With the insane amount of environments, there is no way you can fit it in a lower size without making it into a blurry compressed mess. But to be fair, no device under 128gb would be able to run the game anyway, the graphics are insanely good and some things (like reflections on the road when it's raining) are just a must have that can't be disabled for lower end devices without ruining the feel of the game. Now depending on the optimization of the game, it's either some 128gb devices are strong enough to run it or its 256gb devices at the very least. With the current generation of "AAA" mobile games, 8gb of ram is also probably required.
