You posted a video of Tarkov game play and it didn't escape me that the player making the video spent more than half his time in his inventory screen! I was thinking, that's nuts. GZW is not as bad, Only a few reasons to access inventory in the field, reloading mags, or swapping optics, eating and drinking. I only do inventory management at base or an outpost.
I bought supporter's edition and it gives me the biggest possible stash right out of the gate. In Gray Zone it's just a shortcut, as any player can get the same size, but expansions are gated by player level. Hit levels 10, 20, 30 and get stash increases. Each edition of the game cuts down on this and you get the bigger inventory space straight away. When the game wipes that will be nice. No idea how often that happens in Gray Zone, speculation is the next wipe will be in October but I wouldn't know.
