Idk If IT Works, i Had 8GM Of RAM And Managed to Run It, i Dont Know If 3GB RAM Can run It.
If it took you 10 minutes with 8 GB RAM, I can't imagine how long it would take mine with 3 GB RAM
around 25 minutes i dont know since i dont test with 3 GB ram but i assume its more likely for the game to crash. You can see progress bar when loading the game but you need to go in PC mode in google settings to see it.
