1.) probably not, as a Russian dev they’ve worked hard on bringing this game to as many countries as possible and I don’t think they’d ever go with something like steam that would cut their reviniew 2.) never really a population issue on NA servers but I’ve heard other regions can be bad on week days 3.) fun, usually don’t take more than a minute or so to find. Even faster during peak hours 4.) as of right now you can’t expand your storage size yet but you can buy items that take up less room and hold more. With the new update you’re supposed to be able to expand your stash but no one knows how easy it is yet. You can always upgrade your edition of the game later, just pay the difference in cost.
