So, I’m a bluestacks user.
I started using it when my iPad died, and was no longer able to use the bluetooth keyboard. I tried using the keyboard for a little while with my phone, but that device is on it’s last legs too. After much frustration with scrolling at the pace of a snail, squinting at the tiny screen, dropping out of the game during detailed posts, and typing on that same tiny screen when the keyboard didn’t cooperate (it’s not the highest quality apparently!), I remembered a post I’d read in the forum - Bluestacks or PC version?
I decided to create a mini so that I could chat again in the game. (Though that was ages ago, and my mini seems to keep growing… might have something to do with my E&P addiction!) As mentioned in the linked post, it’s glitchy but still runs ok. It works well enough that I can go into global (and now Peer Support) to help players when I have the time.
As far as other stuff you can do with it, I don’t know. I’ve told other people about me using it for my mini here in the forum, in game chats, and in the moderator thread. Nobody has mentioned until now that it can be linked to other programs, so I’m not sure how well known it is that you can run cheats through it. So as far as I can guess, bluestacks usage is allowed, as long as you don’t violate Small Giant’s terms of service by linking it to something else and running bots, hacks, etc. Bluestacks on it’s own just runs the basic game, just like it does on my iphone, only with occasional missing fonts, and the occasional freeze of the program (a real kicker when you’re in a titan battle!!). So I wouldn’t say that it’s designed to modify or interfere with the service.
I can’t say for sure what SG’s position on the emulator is, but I’ll flag this thread in the moderator chat, and hope that they can give us an answer sometime Monday when they’re back from the weekend.
